Crushed neoprene is heavier (a lot, in my opinion) and takes a lot longer to dry. I have never dived one but haven't heard the "warmer" description before. That's typically a function of the undergarment though I suppose a neoprene suit will automatically have more "natural" warmth than a laminate suit would. I believe, based only on watching other people wearing them, that they are harder to get in and out of due to a lack of material "give" and the overall weight.I currently dive a bare trilam HD which is a front entry. It is a bit large on me so that is the reason for buying a new drysuit. I have never dove a crushed neoprene and would not know the negatives or positives. I have only read that it seems like crushed neoprene may be warmer, while trilam does not "lose" buoyancy at depth or whatever. I honestly have no idea except I know whatever I end up getting will need to work for entry level tech and wreck diving so maybe something which is more durable (sounds like crushed neoprene may win out here?) Again I really don't know.
I've found my trilam suit to be reasonably durable. I wouldn't go penetrating a wreck that had jagged edges or bumping around inside a particularly jagged volcanic cave or something. Even then, I think it would survive a reasonable amount of abrasion, even against fairly sharp objects if you didn't put real pressure on the suit while doing so. That said, it's great for travel, which is why I'm considering a tropical suit as well. If you have a trilam suit, though, you have an idea of how durable the material is already as all the laminates are going to be pretty similar in that regard unless one is particularly "slippery" compared to another.
