One difference: ZipSeals, a zipper-type closure (like a ZipLoc bag on steroids) for neck and wrist seals, which allows you to replace torn wrist or neck seals in minutes. It also allows you to easy add dry gloves with the same zip system. ZipSeals and ZipGloves are available options on DUI suits. You can also get a neoprene neck seal, something I prefer over latex neck seals. DUI is about to come out (sometime in the next few months) with a new compressed neoprene dry glove. I tried on a prototype at DUI Demo Days and this looks like the dry glove equivalent of sliced bread. The compressed neoprene is pretty close to indestructible (which I assume is why you are looking at a neoprene suit anyway), and it looks like it will provide very good dexterity as well. DUI had given the gloves to an instructor at the previous week's Demo Days and had him grabbing everything in sight in a zebra mussel-infested area and the gloves still looked perfect. DUI will also have some thin, but warm, glove liners. DUI is generally considered one of the highest-quality suits on the market, although Bare obviously has its fans. DUI is also known for great customer service. If you can get a deal on a DUI, I don't think you can go wrong.
