The design of the impeller is more important than the material.

However, the important thing is to match your dust collector to your needs and goals. In my opinion, Oneida publishes some pretty accurate performance curves. Also, Wood magazine has done good testing.

You have to decide what you want to do, how much cfm and static pressure you need, what type filtration and then pick a unit. Yes, a lot of work or just buy one and guess.
