What year Dom? if it is a 2010 it has P Rocker which is flat between the feet and rockered outside of the feet. The Skate Banana is rocker between the feet and flat from the feet out...basically they are opposite rocker stories. The Dom won't have the looseness that the Banana has in presses because it has a larger (longer) flat platform that you are standing on. The Banana can def. throw bigger presses without having to fully commit it...other than that, I feel like they are similar on edge (ather than Magnatraction).
If it is an older Dom, it's camber, so it would be quite different than the Banana.
