4-Burner Infrared Grill vs 3-Burner Cast-Iron-Grate Grill: Choose by Cooking Space

Choose the 3-Burner Propane BBQ Grill for its larger 512-square-inch cooking surface and lower listed price, or select the 4 Burner Propane Gas Grill for its four-burner setup and infrared sear side burner.

Last updated Aug 1, 2026

Choosing a propane grill often means weighing more stated cooking space against a burner-and-side-burner setup that suits your cooking style. The 3-Burner Propane BBQ Grill, 30,000 Btus Gas Grill with Cast Iron Cooking Grates emphasizes a larger 512-square-inch cooking surface, while the 4 Burner Propane Gas Grill with Infrared Sear Side Burner for Outdoor BBQ emphasizes four burners and an infrared sear side burner. Their listed prices are separated by $54, so the decision is less about a vast price gap and more about which configuration fits your outdoor cooking plans.

Quick verdict

Pick the 3-Burner Propane BBQ Grill, 30,000 Btus Gas Grill with Cast Iron Cooking Grates when the larger stated cooking surface is the priority. Its 512 square inches give it a 158-square-inch edge over the other grill, and it has the lower listed price.

Choose the 4 Burner Propane Gas Grill with Infrared Sear Side Burner for Outdoor BBQ when you specifically want a four-burner grill with an infrared sear side burner. Its listed 354-square-inch cooking surface is smaller, but the configuration and named side-burner feature are the central reasons to choose it.

Where each grill wins

4 Burner Propane Gas Grill with Infrared Sear Side Burner for Outdoor BBQ

This grill is the better match for shoppers whose must-have is the combination of four burners and an infrared sear side burner. That is a distinct setup stated right in the product title. The silver cart grill also lists a stainless-steel handle. Choose it for a cooking plan centered on that burner count and side-burner capability rather than on maximum stated grill-surface area.

3-Burner Propane BBQ Grill, 30,000 Btus Gas Grill with Cast Iron Cooking Grates

This grill leads on listed cooking surface, with 512 square inches compared with 354 square inches. It also pairs its three-burner configuration with 30,000 Btus, electronic ignition, and cast iron cooking grates in its product details. Choose it when surface area is the more important measure for your cookout setup and when its black finish suits your space.

Product notes

4 Burner Propane Gas Grill with Infrared Sear Side Burner for Outdoor BBQ

The strongest reason to choose this silver grill is straightforward: it combines a four-burner format with an infrared sear side burner. For shoppers deciding between a standard grill layout and a setup that explicitly includes that side burner, the $389.93 option is the direct fit. Its cart configuration, powder-coated finish, alloy-steel frame, and stainless-steel handle round out the listed construction details. The trade-off is its 354-square-inch cooking surface, which is 158 square inches smaller than the 3-Burner Propane BBQ Grill's stated area. It also has the higher listed price, so it makes the most sense when the four-burner and infrared-side-burner combination matters more than larger surface area.

3-Burner Propane BBQ Grill, 30,000 Btus Gas Grill with Cast Iron Cooking Grates

The case for this black grill starts with room: its stated 512-square-inch cooking surface is the larger figure in this comparison. The title also identifies 30,000 Btus and cast iron cooking grates, while the details list electronic ignition, a powder-coated finish, an alloy-steel frame, and a metal handle. At $335.93, it is the lower-priced option of the pair. Its limitation is the listed three-burner configuration when compared with the other grill's four burners. Shoppers who specifically want the infrared sear side burner named on the 4 Burner Propane Gas Grill have a clearer match in that alternative, even though this grill offers more stated cooking area.

Final choice by use case

Choose the 3-Burner Propane BBQ Grill for the larger 512-square-inch cooking surface, cast iron cooking grates, and lower listed price. Choose the 4 Burner Propane Gas Grill with Infrared Sear Side Burner for a four-burner cart grill whose title specifically includes an infrared sear side burner. In short, prioritize surface area with the three-burner grill; prioritize the four-burner, side-burner setup with the silver grill.
