Like other dive equipment, a drysuit is as unique as the individual that is using it. Look at the type of diving that you plan to do as one key as to the type of suit that is best suited for you. I have been down in all makes you speak of, but not all models they offer. The crushed neoprene that DUI offers is tops & resist abrasions great. The neoprene suits are heaver than a trilaminate and in my opinion the trilaminate I believe a bit more versatile as you can use different weight undergarments. They dry faster & are easier to pack. Zip seals are great for what they do but I have found that any glove rings tend to get in the way sometimes. What ever suit you purchase Fit or cut should be top priority.
My current suit is a DiveRite front zip. One of the few that I have tryed off the rack sizes that fit me as it should. Great suit with many options included in their base price. Only thing I need to add is reflective tape.
Hope this helps.
