Ninja FlexFlame Propane Grill vs Blaze LTE+ 40-Inch Gas Grill

Buy the Blaze LTE+ if you want a large, powerful, built-in-style gas grill for high-heat searing and rotisserie work. Buy the Ninja FlexFlame if you want one freestanding unit that also smokes and runs on standard household power. The Blaze wins on cooking area, burner output and stainless build; the Ninja wins on versatility and its long 10-year warranty. Owners of the Blaze praise the sear and the lift-assist hood, while Ninja owners like the multi-mode cooking but note the smaller grate and heavier, bulkier frame.

  • Choose the Ninja FlexFlame if you want a single freestanding cooker that grills, smokes and runs five cooking modes without buying separate equipment.
  • Choose the Blaze LTE+ if you feed a crowd and want maximum grate space, high BTU output and a rear infrared burner for rotisserie.

What reviewers say

Blaze LTE+ 40-Inch Gas Grill

Owners of the LTE+ line praise the even heat, the searing rods and the spring-assisted hood. Complaints center on the grill's weight and the modest output of the rear infrared burner.

What people mention
  • Heat outputPraisedOwners say the five main burners reach searing temperatures quickly and hold them.
  • Searing rodsPraisedThe triangular 9mm rods are credited with deep, steakhouse-style grill marks.
  • HoodPraisedThe spring-assisted hood and the lights it switches on are called a genuine convenience.
  • WeightCriticisedAt 139 lbs the grill is hard to move, even on casters.

Questions and answers

Which is better for smoking?
The Ninja FlexFlame. It has a dedicated smoker mode and a 200°F low end. The Blaze is built for high-heat grilling and rotisserie, not low-and-slow smoking.
Which has more cooking space?
The Blaze. Its 915 sq. in. is more than double the Ninja's 424 sq. in. main grate, so it handles bigger parties.
Which sears better?
The Blaze. Five 14,000 BTU burners and 9mm triangular stainless rods deliver more heat and sharper sear marks than the Ninja's three burners and cast iron grates.
Can I use natural gas with either?
Only the Blaze. It ships with interchangeable propane and natural gas orifices. The Ninja FlexFlame is propane only.
Which lasts longer?
The Blaze's heavy stainless cart and cast stainless burners point to a longer service life, but the Ninja backs its unit with a 10-year warranty, which the Blaze listing does not state.
Is the Blaze worth stepping up to?
Yes if you regularly cook for a crowd or want rotisserie. If you want one unit that also smokes and costs less to run on household power, the Ninja is the more flexible pick.
