Nothing on this list will disappoint.
Fire Magic Echelon Diamond 36-Inch
If you ask someone to give you the names of the best of the top of the line appliance manufacturers, the name Fire Magic probably won't come up. Yes, they only make appliances of the outdoor variety, but they stand head and shoulders above the more famous brands. The reason for this is their dedication to the quality of the manufacturing, their relentless innovation, and the sheer devotion of their staff. This model runs over $5,000USD but is one of the best gas grills ever made. It's three main cast stainless steel burners can produce 99,000 BTUs under 792 square inches of heavy stainless cooking surface. This gas grill is one of the most powerful on the market. Add in a full rotisserie system and this unit is the masterpiece of any outdoor kitchen (and Fire Magic has one of the most complete lines of outdoor appliances).
Twin Eagles 42-Inch
This great looking 304 stainless steel gas grill is not only beautiful to look at but a master of engineering. Twin Eagles manufacturers one of the best lines of outdoor cooking appliances and this is the cornerstone of that line. Every detail from the distribution of heat to the polished seams has been thought out with obsessive detail. This three burner unit generally sells for a little over $5,000 and comes with a rear mounted infrared rotisserie burner and any of the main burners can be swapped out with an infrared searing burner. There is a lot of versatility to this grill and a host of extras can be added on.
Alfresco ALXE 36-Inch
Just as an example of how well this gas grill is built, the rotisserie is driven by a chain system that is completely invisible from the outside. Load up the rod with as much food as will fit (it can take the weight) and drop it into the unit and fire up the rear mounted rotisserie burner. The whole operation is seamless and easy as is the rest of this grill. This three burner model also has an integrated smoker box with dedicated burner and any of the main burners can be swapped out with infrared. The standard burners, however, can pump out up to 125 BTUs per square inch (the same as the Fire Magic above). This is a well engineered and powerful grill that can last for years easily.
Capital Precision 40-Inch
Capital Cooking has been in the gas power appliance business for decades. Their lineage goes back to the first Viking gas range built for the home, through the founding of DCS and to the first all stainless steel gas grill for the backyard. Like the other products on this list, the Capital Precision has a high level of engineering and elegant design. This model features cast stainless cooking grates, a full rotisserie system, two standard 25,000 BTU burners and one 25,000 BTU infrared burner.
DCS Heritage 36-Inch
No list of the best gas grills would be complete without a model from DCS (Dynamic Cooking Systems). As one of the original companies in the market space and after having produced half of the innovators in the industry, these grills are some of the best money can buy. This three burner unit can produce up to 75,000 BTUs under 638 square inches of angled cast stainless steel grilling surface. The configuration of this particular model (which can be customized as needed) includes a solid stainless steel griddle, standard burner, and an infrared searing burner. There is also a full rotisserie system included. DCS also makes one of the most extensive lines of outdoor cooking appliances and features.
Lynx Professional 36-Inch
If you have been reading through this whole list you will probably notice that while these are all fantastic grills, there isn't a lot of variation. This model from Lynx is true to that. The most innovative feature of this grill is the ProSear Trident burner, one of the best infrared burners on the market. This E-type burner isn't a single sheet of ceramic, but a three prong burner which optimizes and evens the heat. Infrared burners tend to be hottest in the center and cool the farther you get from that. Not this burner. In addition to this, this Lynx Gas Grill has a full rotisserie system, elegant styling and solid 304 stainless steel construction.
Hestan has changed the game of high-end outdoor grills and taken the industry by storm in the last few years. The superior, heavy construction of their grills makes them a fantastic choice for any outdoor kitchen application. This 36-Inch grill head weighs in at 280 pounds, making it one of the heaviest model on this list and it comes in multiple colors (and all stainless steel of course). The stainless steel cooking grates are cut from 5/16-inch thick plate and the three trellis burners can produce up to 75,000 BTUs under the 653 square inches of primary grilling space. The rotisserie burner is mounted above, for top-down broiling and can be used as a powerful salamander for a wide range of cooking. This is a beautifully detailed grill and one that I am sure will be climbing a few spots on this list in the years to come.
American Muscle Grill 36-Inch
Pushing the price limit of this list is the aptly named American Muscle Grill. This powerhouse not only has the ability to produce 110,000 BTUs under 720 square inches of cast stainless steel cooking grates. As impressive as this power is, it isn't the best feature. This is a complete hybrid grill, meaning it can burn gas, wood, charcoal, or practically anything that burns. The only other gas grill with this capacity is the Kalamazoo Grill, which of course, costs more than twice as much. This grill also features a top mounted rotisserie burner like the Hestan above and is styled to look something like a 1969 Shelby Mustang GT 350.
PGS Legacy Pacifica Gourmet 39-Inch
On the opposite of the price spectrum, sits this gas grill from a company that goes back to the days of the first gas grills. Typically selling for just over $4,000, this isn't a discount brand or a cheap grill. The three main burners produce as much as 75,000 BTUs under 720 square inches of stainless steel grilling space. While not necessarily the most innovative of grills, this unit does have a full rotisserie system with a rear mounted infrared rotisserie burner.
Solaire by Rasmussen Iron Works is another venerable brand. They started out focusing on infrared grilling in competition with TEC (the inventors of the technology). While a basic design, this is a powerful and capable line of gas grills. This 42-Inch model boasts 667 square inches of V-shaped stainless steel cooking grates. Burners are available in any combination of infrared or standard and this unit on high can hit nearly 125 BTUs per square inch. As a line of products for an outdoor kitchen, Solaire is a little limited, but they have a strong reputation for a great line of gas grills.
TEC Sterling G3000 FR 36-Inch
TEC invented infrared cooking, particularly the infrared grill. When their patent ran out, they reinvented it. This very unique, all infrared gas grill uses plates of tempered blue 'glass' to convert 100% of the heat produced by its three 16,000 BTU burners into incredible levels of heat. On high, this grill can produce cooking temperature approaching 900 degrees F while still able to drop down to 350 degrees. A TEC grill is the ultimate searing machine and while the overall cooking versatility can be a little limited, it is an amazing gas grill.
Caliber Crossflame Pro 42-Inch
The heart of any gas grill is in the burners. The burners on this Gas Grill from relative newcomer Caliber are solid cast brass. While this has been a favored material for gas grill burners, it is seldom used these days. But more than just having brass burners, the Caliber uses a design that creates an even flame under the entire cooking surface (which is 805 square inches of stainless steel on this model). This model also contains one infrared searing burner and a full, hidden rotisserie with rotisserie burner and lights that not only cover the grilling surface, but the side areas as well. At nearly $6,000USD (typical sale price) this is a serious contender in the industry.
I include this model gas grill with Wolf, one of the top professional and residential appliance makers, not just because it is an excellent unit, but because it illustrates the truth about many of the big 'indoor' appliance brands. This grill includes everything you expect from something in this price range (it typically sells at just under $6,000USD). It has three 25,000 BTU burners, infrared options, a full rotisserie system, and internal lights. This issue is that this gas grill is made by Twin Eagles (see the second item on this list), which is a good thing since Twin Eagles makes some of the best gas grills in the world. The problem is, this model costs about $1,000USD more than a comparable Twin Eagles grill and doesn't offer anything extra besides a recognized brand name.
