Lion L90000 vs Summerset Sizzler: Which Grill Delivers More Sizzle for the Price?

Shopping for a serious outdoor grill and torn between the Lion L90000 vs the Summerset Sizzler? 

These two 5-burner gas grills are among the most talked-about options for backyard chefs who want power, size, and durability without jumping to the ultra-premium tier.

In this in-depth comparison, we’re breaking down both the freestanding carts and built-in models to give you the full picture. Whether you're planning a full outdoor kitchen or want a mobile cart that’s ready to fire up steaks for 20 guests, this article covers everything you need to make the right call.

Let’s see how these two heavyweights stack up on features, performance, value, and which one actually delivers the better backyard grilling experience.

Much like its name, the Lion L90000 is an absolute beast. It features 16-gauge 304 stainless steel throughout, including the firebox, grates, burners, and even the hood. This is top-tier, commercial-grade material that resists corrosion and heat discolouration, a key reason Lion fans often call it “the heaviest grill in its class.” The double-walled, seamlessly welded hood provides excellent insulation and structure, keeping heat in and the elements out.

Its freestanding version is just as rugged, weighing a whopping 319 lbs, and comes with sturdy dual drawers, a storage door with gas ventilation, and locking caster wheels. Even the included shelves are stainless steel with built-in hooks and a bottle opener, which are small but thoughtful touches.

The Summerset Sizzler 40-Inch, meanwhile, uses 443 stainless steel for the main body and 304 stainless steel for the freestanding cart. While 443 SS offers decent corrosion resistance, it’s not quite on the same level as 304, especially in humid or coastal environments.

The Sizzler’s redesigned hood and cart look great and feel sturdy, but it’s a slightly thinner gauge of steel overall. Still, it holds up well with a double-lined hood to prevent warping and discolouration over time. The cart offers folding side shelves, access doors with magnetic latches, and convenient extras like a paper towel holder and propane tank storage. It’s functional, no doubt, just not quite as solid as the Lion.

The Lion L90000 boasts five cast stainless steel burners pushing out a total of 75,000 BTUs, which is among the highest in its class. These aren’t hollow tube burners, they’re thick, durable, and designed to retain heat better over time. The heat spreads evenly across the 802 sq. in. main cooking area, with flame tamers and heavy-duty grates helping reduce flare-ups while keeping temperatures steady.

Where Lion really shines is searing and high-heat grilling. You can get this thing blazing hot in under 10 minutes, making it ideal for thick steaks or caramelising sauces. It also includes a powerful 15,000 BTU rear infrared burner for rotisserie cooking, something you’ll rarely find at this price point without an upgrade.

Over on the Summerset Sizzler, you’ll find five high-performance stainless steel tube burners delivering a total of 70,000 BTUs, slightly lower than Lion's, but still more than enough for high-heat grilling. The Sizzler also heats quickly and evenly thanks to well-designed 443 stainless flame tamers, which help reduce flare-ups and distribute heat across the surface. It’s great for grilling burgers, kebabs, and chicken.

Unlike Lion, an infrared rotisserie is not included with the Sizzler, it’s available as an optional upgrade. That’s something to consider if you want rotisserie cooking as part of your outdoor game plan.

The Lion L90000 is packed with thoughtful features for its price. It includes two internal grill lights, which come in handy for nighttime cooks. The XL temperature gauge on the hood is easy to read and helps with precision grilling without lifting the lid. You also get six independent Quick-Lite valves, allowing total control over each burner.

And let’s not forget the extras: the griddle plate, rotisserie kit, and smoker box are all included in the box. This makes it an extremely well-equipped grill for both beginners and experienced grillmasters. The freestanding version even adds a paper towel holder, dual storage drawers, bottle opener, and locking casters, making it feel like a full outdoor kitchen on wheels.

In contrast, the Summerset Sizzler 40-Inch goes for a cleaner, more minimal design with some tech-minded improvements. Its flame thrower ignition system is reliable and battery-free; just push, turn, and you’re grilling. It also has a manual flash tube ignition as a backup, something many entry-level premium grills skip. The 3-inch built-in analogue thermometer is large and accurate, and the double-walled hood not only retains heat but also resists discoloration over time.

The Sizzler cart model adds some premium touches like fold-down side shelves, locking casters, propane tank storage, and even a built-in paper towel holder. However, many of the features that come standard on the Lion, like interior lights, smoker box, and rotisserie, are only available as upgrades on the Sizzler.

The Lion L90000 40-inch is built for flexibility. With a massive 1,030 sq. in. of total cooking space (including a generous warming rack), this grill easily handles up to 32 burgers at once. Whether you're searing steaks, roasting a whole chicken on the included infrared rotisserie burner, or using the smoker box to add wood-fired flavor, the Lion is ready for it.

It also comes with a removable griddle plate, opening up options for breakfast foods, veggies, or flat-top style burgers, something most grills at this level don’t offer out of the box. And since the burners are individually controlled with six quick-lite valves, you can do multi-zone cooking, crank up one side for searing and leave the other low for indirect heat.

The Summerset Sizzler 40-Inch, while slightly more compact at 875 sq. in., is still a powerhouse. It has excellent heat distribution and 443 stainless flame tamers that vaporize drippings for enhanced flavor. You can also multitask effectively: grill your main dishes on the large primary surface and keep buns or veggies warm on the upper rack.

If your grilling style is mostly burgers, chicken, or steaks with the occasional indirect cook, the Sizzler does the job beautifully.

The Lion L90000 is built with heavy-duty stainless steel flame tamers and solid stainless steel grates that hold up well to frequent cleaning. The grates are thick and durable, making them easy to scrape down after cooking. The grill also has a full-width drip tray that slides out from the front, which catches grease and debris efficiently. It’s not flashy, but it gets the job done, and it’s easy to access.

The Summerset Sizzler also features 443 stainless steel flame tamers, designed to catch drippings, vaporize them into flavor, and protect the burners underneath. Users report that these tamers are effective in minimising flare-ups and channelling grease toward the drip tray.

The grates are slightly thinner (8mm rods) than Lion’s but still strong and easier to handle for cleaning. The Sizzler has a removable drip tray as well, but it’s tucked in slightly deeper, which can be less convenient depending on how your grill is installed.

When it comes to flare-ups, both grills manage them well, and the flame tamers on both models do a solid job. That said, Lion’s heavier construction tends to offer a bit more protection and easier cleanup after long cooks. Also, Lion’s included smoker box and griddle add versatility but can require extra scrubbing after heavy use, so that’s something to factor in if you use them often.

When you’re comparing two 5-burner grills that both look the part and pack serious heat, it often comes down to what you get for the price and how long it’s going to serve you.

Lion L90000 tends to be the better deal on paper. At around $2,199 for the built-in version and $2,800–$3,000 for the cart, you’re getting premium 304 stainless steel, cast stainless steel burners, 1,030 sq. in. cooking space, and extras like an infrared rotisserie, griddle, smoker box, cover, and even interior lights. That’s a hefty package included in the base price, as many competitors charge extra for these add-ons.

Summerset Sizzler 40-Inch, on the other hand, runs about $1,849 for built-in and $2,700 for freestanding. It’s a newer model and has a cleaner design, great build quality (443 stainless in the body, 304 on the cart), and thoughtful cart features like folding side shelves, a towel rack, locking casters, and a built-in paper towel holder. However, accessories like the rotisserie kit or griddle cost extra.

Warranty-wise, both brands offer lifetime coverage on main components like burners, flame tamers. But Summerset goes a step further with a Gold Standard Lifetime Warranty, which also includes valves and temperature gauges. Lion’s warranty covers burners, frame, housing, and grates for life, with 3 years on flame tamers and 1 year on valves and parts.

Looking at long-term ownership, users often report Lion holding up well after several seasons, even in harsh climates. It’s heavier, thicker, and built more like a tank. Summerset is no slouch; it gets high marks for ease of use and solid construction, but a few users noted the 443 steel shows cosmetic wear a bit sooner near salty or humid air.

If you're down to these two, you’re already in good territory, but here’s how to break the tie.

Bottom line? If you're after raw value and grilling muscle, go with Lion. If you're building out a clean, modern outdoor kitchen and don’t mind paying more for aesthetics and modularity, Summerset delivers.
