Product notes

4-Burner BBQ Gas Grill with Side Burner, 42000 BTU Stainless Steel Outdoor Grill

This 4-burner propane grill is the pick when you want a dedicated side burner for heating sauces or sides while the main grate is full. The listed features also include piezoelectric ignition for startup, and the assembled footprint is listed at 46.5"L x 21.85"W x 40.9"H, so it needs a defined spot on your patio. The trade-off is that footprint: this is a larger grill that takes up real outdoor space, so be sure you have the room before committing to it.

4 Burner Gas Grill with Cast Iron Grate Stainless Steel Pan, 40000 BTU BBQ Grill

The Cookit 4-burner grill is the pick when you want a built-in thermometer and a foldable body. It also lists wheels and a freestanding design, so you can move it around your outdoor space. The cast iron grate and stainless steel pan are part of the package, and the model arrives ready to be assembled. The main limitation is that assembly is required before first use, so set aside time for setup. If you want a grill that can be tucked away when not in use, the foldable design makes this Cookit the more convenient option.

Final choice by use case

Choose the higher-priced model when you're planning bigger cooks and need more capacity from a 4-burner grill. Choose the Cookit when you'd rather keep the list price down and still get a flexible grill for everyday outdoor cooking.
