Which is better for car sound deadening?

The NOBRAND roll, because you can pick 10mm or 20mm thickness and cover a larger area. The neoprene sheet is only 1/4 inch and better suited to small patches.

Neoprene resists oil, heat and wear better than PVC foam, so the neoprene sheet should hold up longer in harsh spots. PVC foam can tear or compress over time.

Is the neoprene sheet worth the extra over the foam roll?

It is actually cheaper at $15.49 versus $19.98, but you get less area and only one thickness. Pay the extra for the roll if you need coverage; take the neoprene if you need toughness.

Can I use either one on an engine hood?

The NOBRAND roll is marketed for hood and engine bay use and comes in thicker sizes. Neoprene handles heat well but 1/4 inch gives limited thermal blocking.

Which is easier to cut?

The neoprene sheet is thin and flexible, so it cuts easily with scissors. The thicker NOBRAND roll cuts fine with a sharp blade but takes more effort at 15mm and 20mm.
