I have a Bare XCS2 Tech dry suit and a Waterproof D9X, which is a breathable quad-lam.
The Bare is crushed neoprene with a diagonal front zip. I can easily don/doff it with no assistance.
The crushed neoprene is definitely warmer than a tri- or quad-lam and offers the possibility of using slightly less bulky undergarments.
And the crushed neoprene is VERY durable.
But, unless I actually think I will need that durability, I would wear the quad-lam suit any time, for any dive. The reduction in undergarments that are needed for the crushed neoprene is offset by the increased bulk of the suit itself. On dives where surface air temperature is anything over about 70F, if the dive plan is for water that is below 50, then I am miserable gearing up and wearing the neoprene suit on the surface. It is heavy and hot. I find the quad-lam to be much more comfortable to wear on the surface and actually more comfortable and easier to manage buoyancy and trim as well. And the telescoping torso and much more flexible material of the quad-lam definitely makes it easier for things like reaching back to my tank valves.
The neoprene suit doesn't squeeze down and shrinkwrap itself around me like the quad-lam suit does in the water. I think this results in the neoprene suit having a little bit more air inside during the dive, which makes it slightly more difficult to manage. But, with the right undergarments on, I am equally comfortable even in the 37F water of my local quarry.
