Which is better for searing steak?

The E-325s. Its page claims the largest and hottest sear zone in the Genesis line, while the E-315 uses a standard three-burner layout.

Is the E-325s worth the extra money?

If you want a sear zone, an expandable top grate and a prep table, yes. At the recorded lows the gap is about $222, so it depends on whether you will use those features.

Which one has more cooking space?

The E-325s adds an expandable top grate on top of the main surface, so it can cook more at once. The E-315's main surface is large but single-level.

Can I get either one in propane?

The E-325s comes in propane or natural gas. The E-315 is listed as natural gas only.

Both are Weber Genesis grills with the same brand warranty backing, and no lifespan figures are published for either, so neither is clearly longer-lasting.

Does the E-315 come with a propane tank?

No. The listing says the liquid propane tank is sold separately, and the E-315 is a natural gas model anyway.
