The Viking bayonet system is different from the others in two ways that I know of: One, it is simplicity itself to install, without any tools, and you can swap out a leaking glove in the parking lot in about the same amount of time (again without tools). Second, it is a positive lock system. Once you have the rings properly positioned and rotated, the glove CANNOT pop off. Unlike many of my dive buddies, I have never had a wet hand from anything but a leaking glove. And you can mount a variety of gloves on the Viking rings, although most of the people I know use either the blue or orange Atlas gloves. But Peter uses a thin neoprene glove, and dsteding uses a thick neoprene dryglove. You have a lot of choices.
Getting bungied gauges over the wrist rings can be a bit of a PITA if you use the thick bungie. I use thinner stuff, and it's not a problem.
