Which is better for searing steak?

The Napoleon, because it lists an infrared burner built for high-heat searing. The Weber has no infrared burner listed, so searing relies on its standard burners.

Which has more cooking space?

The Weber. It is 65 inches wide with four burners versus 55 inches and three burners on the Napoleon.

Can I use the Napoleon with propane?

It is listed as natural gas. Running propane would require a conversion kit, so check before buying if you have no gas line.

Which is better for rotisserie cooking?

The Napoleon, which includes a rotisserie. The Weber's listing does not include one.

Both are stainless steel and neither listing states a warranty, so longevity depends on care and cover. Check each brand's warranty terms before buying.

Is the Napoleon worth more than the Weber?

No prices were provided, so that can't be judged here. The Napoleon adds infrared and rotisserie; the Weber adds a burner and width. Compare current store prices on both.
