I would have to say.....
- The one that keeps your hands dry
- THe one that doesn't let water in your suit if the glove gets cut or leaks
- The one you find easiest to use
- User-friendly ease of replacement
- Removable liners for ease of de-stinkifying
I happen to have the DC rings with the blue smurf yellow fuzzy lined gloves. I need to fix 'em so they have an inside wrist seal. My next pair of replacement gloves will definitely have removable liners! I've also found it's imortant to periodically lube the O-ring for ease of donning/doffing. It's not user-friendly to put new gloves on the rings, but after doing it a couple times, it doesn't take as long.
