closed cell sponge neoprene seal compared to solid neoprene

Is there much of a performance difference between these two door seals? One has a seal that is a solid neoprene bulb and the other is a closed cell sponge neoprene.

Since they are both made by Zero International, why not call them directly and ask them which is more appropriate for your build? They have good people who can help you decide. - Stuart -
