In the neighborhood you’re known for your grill game. You’re the rib-master, the steak king or the burger boss.

When you’ve earned the title of grill master, you need a grill to match your skills.

A 3 burner and even 4 burner grills are great for rookies, but once you’ve moved on to the next level, the 6 burner grill becomes the new frontier.

Final Sear

The Final Sear: The Weber Summit S-670 is the top pick for the 6 burner group. Front and center: you get almost 900 square inches of combined cooking space, burners dedicated to specific functions, like searing, smoking, and rotisserie, and the unbeatable Weber quality and durability. 

For the casual griller, the 6-burner is going to be overkill, but the extra space can be a really great bonus when you’re firing up the grill every weekend or to feed a small army of friends and family.

The extra square inches and bonus burners give you a ton of versatility, allowing you to cook meat and sides at different temperatures, no over or undercooking guesswork to deal with. You can even dedicate a burner just to searing!

So let’s dive into the best 6 burner gas grills on the market and get you searing those juicy delicious steaks.

1. Weber Summit S-670 Stainless-Steel Gas Grills

The Weber Summit 7470001 S-670 Gas Grill is so good, it’s almost a work of grilling art. This is where form meets function and you enjoy one truly top level grilling experience in an aesthetically-minded package.

The name Weber is essentially synonymous with quality and durability. The company is known for designing some of the best gas grills in the market, across a vast range of price points.

With six stainless steel burners, including an additional side burner, sear station burner, smoker burner, and rear-mounted infrared rotisserie burner, you can cook almost anything you would ever want to eat all in one massive unit. It offers a total of 838 square inches and 60,600 BTUs for a powerful experience. Grilling grates are solid stainless steel for the best heat conduction and easy clean up.

Weber’s burner tubes are widely regarded as some of the highest quality on the market, with a seamless stainless steel design without welds for extra strength and integrity. Infinite control settings on the burner valves allow for the utmost calibration of temp so you can really elevate the experience and fine-tune your cook.

It also comes with Weber’s signature flavorizer bars for capturing the aromatic juices of the meat and two stainless steal workspaces for prep and a finished meat resting area. The lower double door cabinet is pretty massive and has ample room for storing all your grilling essentials alongside the propane tank.

The Summit’s body is primarily made up of stainless steel so it’s especially durable. This grill also boasts an individual ignition system for each separate burner, so you do not have to light the whole thing just to cook one or two small items, adjusting the temperature of each burner to suit whatever you’re grilling, whether it’s salmon or a New York strip.

This model is also equipped with all the usual features like a push-button ignition, easily removed angled grease management system, lid-mounted thermometer and a propane monitoring gauge so you know where you stand with your fuel.

The main control panel is illuminated for easy grilling in low-light conditions.

You can either get the Summit as a propane gas grill model or hook it up to your home and run it on natural gas – it also ranks as one of our picks for the best natural gas grills.

While the Weber may empty out your wallet a little more thoroughly than some of the other grills on the market, its durability is a return on the investment.

2. Napoleon PRO665RSIBPSS-3 Prestige PRO 665 RSIB Propane Gas Grill

When it comes to higher end grills, Napoleon makes some of our favorites for both easy of use and years-long durability. Like the Weber, the Pro series are all investment grills that will elevate your backyard grill time to an experience.

This particular series comes in a range of sizes with different burner offerings, but the 6 burner we are looking at for this list is a serious luxury option. There is very little it doesn’t offer and if you have the cash to throw at something seriously badass, this is where you can put it.

So let’s start with the core functionality. The Pro 665 comes with 5 primary burners. It also includes dual-level infrared sizzle zone side sear burners for max temps as well as a rear infrared burner. It’s really designed to function as an outdoor kitchen so you can cook an entire meal on it, including mains, sides and even dessert if you’re feeling wild.

In terms of power, it brings 99,000 BTUs to the table and it is pretty massive at 1,140 total square inches of cooking space. I don’t think you could fill all of that up in one go even if you tried. That’s almost 300 square inches more than what the Weber Summit is offering.

Napoleon also includes all the standard and non-standard luxury features you could expect at this price-point: matchless push button ignition with an extra fast heat up, a lid-mounted thermometer for each lid/cooking zone, a truly beautifully designed roll top lid, an infrared rotisserie burner, and an integrated smoker tray so you can convert your grill set up into a smoker with it’s own dedicated burner.

The power side burners have reversible cooking grids and are designed to handle sauce and side prep as well as searing off steaks.

One of my favorite features are the interior lights for seeing what you’re grilling even at night and lighted control knobs that you can customize to your preference with a bunch of color options. There’s also a nice safety feature where knobs will glow red when the gas isn’t fully turned off.

The overall design of the Napoleon is shiny and it’s pretty breathtaking for something so functional and beastly. Stainless steel and chrome finishings are used liberally throughout. The lower cabinet includes shelving so you can store all your tools plus a few extras alongside the propane tank.

There truly are no drawbacks to this grill, it is a performance piece of machinery meant to provide an outstanding experience on every level. If you have the budget to spend and aren’t quite ready for the behemoth that is the PRO825, this is an exceptional choice.

3. Broil King 957344 Regal XLS Pro LP Gas Grill

The new model of the Regal XLS is a solid upgrade for 2020 and offers another contender with a slightly more wallet-friendly price tag.

The name “Regal” is dead-on for this grill. It is massive, shiny, and updated with pretty much every bell and whistle Broil King could think of the elevate the grilling experience for die-hard fans.

Of the three in our top spots, the Broil King is the least expensive, but it still packs in the best feature list and should be your go-to if you have a healthy budget and are looking for an insane grill experience.

Let’s kick this off by looking at size. The Regal offers 750 square inches of primary cooking area with an additional 250 square inches of warming rack for keeping your veggies hot and toasting up some buns if you’re enjoying a day of burgers. It features stainless steel cooking grids in the main oven compartment and cast iron grids in the secondary cook box.

The overall power of this beast is also impressive, though not as jacked as our other two top grills, with 60,000 BTUs for the six main burners, a 10,000 BTU commercial grade infrared side burner AND a dedicated 15,000 BTU dedicated stainless steel rotisserie burner, with the kit included. The dual lids and cook boxes make for a sweet set-up.

Broil King’s signature Flav-R-Wave cooking system is designed to vaporize drippings and infuse the flavor back into whatever you’re grilling while simultaneously delivering consistent, even heat.  The linear flow valves are also optimized to give you measured temperature control for a nuanced grilling experience.

This model features electronic ignition and a front-mounted temperature gauge. The overall build is primarily stainless steel, with chrome detailing on knobs and fixtures for ultimate durability. The knobs are also LED illuminated for evening grilling, so when it’s getting dark and you’re just not ready to call it quits, you can keep your grill session going.

The storage situation on the XLS is solid with drop down stainless side shelves that include tool hooks, shelf slots and towel racks. The three under cabinets are perfect for storage and concealing the slide out mechanism for the propane tank, another detail feature we love.

Grillers on Amazon are die-hard fans, raving about all the features and the smooth experience for grilling with an overall rating of 4.1 out of 5 stars.

4. Royal Gourmet 8-Burner Liquid Propane Event Gas Grill

This 8-burner behemoth from Royal Gourmet isn’t really designed for the casual backyard grillman. This grill is more suited for large event spaces, like church bbqs, picnic spaces or event halls.

The Royal Gourmet Event Grill features 8 stainless tube burners, 104,000 BTUs of total cooking power, 2 regulators for the propane system, 950 square inches of total cooking space and porcelain-coated cooking grates. It also includes a stainless steel control panel for extra durability, an electronic ignition system, and large capacity grease management system.

Since this grill is designed to feed a small army, it also has roomy side shelves for prep and two lower shelves for serious storage. It comes with a giant cover to keep it protected from the elements and is a great pick if you’re regularly in the habit of feeding a small army.

5. Monument 6 Burner Propane Gas Grill in Stainless

This is a solid grill from Monument and a massive addition to any backyard grilling experience.

It includes 6 stainless steel primary burners spread over 634 square inches of primary cook space in addition to the 266 square inch warming rack. It also includes an additional side burner for sauce or side prep. Overall power is an impressive 84,000 BTUs, the max on this list.

The Monument also offers a stainless steel design with stainless lid and cook box, stainless steel cooking grates for even heat distribution, stainless steel flame tamers, electronic ignition system, LED control knobs, and zinc plated, removable grease tray for easy maintenance.

It is mounted over a roomy lower cabinet designed to conceal the propane tank and offer additional storage. This is a great pick if you’re looking for a ton of cook space for your money.

6. Royal Gourmet Mirage MG6001-R 6-Burner Gas Grill

Royal Gourmet has a great line up of grills and this is another solid, and massive addition.

The Mirage offers 465 square inches of primary cooking space, a 90 square inch warming rack, porcelain cast-iron cooking grates with a specialty slope design to lock in flavor, stainless steel tube burners, two separate stainless lids with built-in thermometer gauges.

Total BTU output is 96,000 for all burners, including the infrared rear burner and shelf-mounted, lidded side burner. The build is primarily stainless steel with a huge under-cabinet, sliding tank rack and two side shelves with tool hooks for storage.

7. Weber-Stephen Company Genesis II S-435 NG Grill

The Genesis II S-435 is a little smaller than some of the other grills on this list, the 6 burners for this one include the side burner and the sear station burner. It only includes 4 primary burners with 48,000 BTUs of combined output. The sear station burner has 9,000, with 12,000 on this side burner.

It includes stainless steel cooking grates, Weber’s signature Flavorizer bars, an easy-access grease management system, generous lower cabinet storage with rack style shelving, two side tables with tool hooks and the lidded side burner, as well as a front-mounted temperature gauge.

The S-435 is primarily stainless steel construction with chrome finishings. Like all Weber grills, it is designed to last.

8. Char-Broil Performance 650 6-Burner Cabinet Liquid Propane Gas Grill

This roomy offering from Char-Broil is a top pick for sheer size for the price value on this list and is a great pick if you’re not yet ready to splurge on a Weber.

The Performance 650 offers a mega-sized primary cooking are at 650 square inches and an additional 280 square inches of secondary warming rack for buns and veggies. It comes with 6 primary burners, plus a 10,000 BTU lidded side burner. Main burner power comes in at 60,000 BTUs. It also comes with electronic ignition for quick and easy start-ups and a built-in lid-mounted thermometer.

Overall construction and fascia is stainless steel, with a large lower storage cabinet for tools and to hide the propane tank. Stationary steel side shelves provide for extra prep space. This is a great offering from Char-Broil and one of the bigger units in their Performance line up.

9. Bull Outdoor Products 62648 Diablo 6 Burner Grill Head

If we’re talking 6 burners, we have to include at least one of my favorite built-in options. Bull is the king of built-in grilling and this 6 burner grill head is a beautiful addition to a built-in backyard kitchen set-up.

The Diablo is their largest model at 105,000 square inches of grilling area for 6 cast stainless steel burners running at 15,000 BTUs each for a combined 105,000 BTUs of total power. There’s also a bonus infrared back burner that’s ideal for perfect precision searing.

Bull includes their “relia-bull technology” which guarantees even heat distribution by using specially designed flame tamers (thanks to the geniuses they hired at Cal-Tech) to create a more even grilling surface that better eliminates hot and cold spots. They claim this improves heat distribution by up to 50% and allows you to use the whole surface with incredible consistency.

Construction is 16 gauge 304 stainless steel, which is professional level and zinc knobs that are perfectly fitted. This is Bull’s luxury grill head and the top of their line so every piece is top-quality.

If you’re looking for the biggest, baddest 6 burner grill head on the block, you’ve met your match with this guy.

10. Weber Stephen Company 63014001 Genesis II LX E-640 Liquid Propane Grill

The E-640 version of the Genesis is an incremental upgrade on the S-435 we talked about in the #7 spot and the E-610 in our very top spot. The outer construction and inner workings are almost identical, with a few small upgrades.

What can you expect to see enhanced on the E-640? The overall cooking size is larger at 770 square inches (same as the 610). The power is also amped up on this model, with 72,000 BTUs for the main burners (the 610 has 69,000), but the side burner remains the same at 12,000 BTUs. The only other upgrade is a second handle light (the 435 only has one), which is a pretty minimal bonus.

If you’re considering this model, it’s really only to get some extra cooking space and a little more power over the S-435 and E-610 versions of the Genesis. Reviews from other users are consistently strong for both models.

I am a grill freak! It's hard to pick my favorite thing to grill, but if I had to choose... it is still a tie between pork ribs and a juicy beef burger. I am currently grilling on a Weber S210(I live in a small space) but my dream grill is definitely a summit. Those things are bad ass. Anyways I would love to hear from you, leave a comment or question below!
