Which is better for a backyard with a gas line?

The Spirit S-425. It runs on natural gas, so you never refill a tank, and its stainless cabinet hides the hookup and tools.

Which has more cooking space?

They are the same. Both give 428 sq. in. primary and 533 sq. in. total, though the EP-435 lists room for 21 burgers versus 15 on the S-425.

Is the EP-435 worth the extra when it spikes to $799.00?

No. At $799.00 it costs far more than the $500.00 S-425 for the same cooking area. Wait for it to fall back toward its $292.50 low.

The S-425 has a stainless lid, control panel and cart door, which generally holds up better outdoors than the EP-435's metal body and enclosed lid.

Can I take the EP-435 camping or tailgating?

Yes. It runs on a propane tank and is listed as portable, while the S-425 is fixed to a natural gas line.

Do both have a sear zone?

Yes. Both use Boost Burner knobs that add 40% more power in the Sear Zone, plus Snap-Jet ignition and stainless Flavorizer Bars.
