I've used or played with the DC, Sitek and Viking systems, and I much prefer the Viking bayonet rings. They are easily installed on the seal, without tools, and equally easily removed. Changing gloves is equally simple and can be done in the field, if you have spare gloves with you. You can use the Atlas gloves, which are inexpensive and for me, locally available. The things are bulky, but I haven't seen a system where the rings are really any less so, except the ones where the gloves have the seal on them, and those are reportedly a PITA to get on by yourself (not to mention that the gloves are expensive!)
No ring system is really going to make the arms of the dry suit any longer, but if you pull your seals a bit up your wrist, you can use the glove length to compensate for the increased distance from seal to fingertip.
I followed Lynne's suggestions and got the Viking bayonet rings. I am very, very happy with them and always chuckle when people 'fight' on a boat with their Dive Concept (DC) or Si-Tech rings.
The advantage of the Vikings is IMO that you use the thumb and index finger of the other hand to turn the rings against each other for locking. On other systems you have to push or turn the glove ring against the floppy sleeve of the suit; that's where you then see people sticking their arm between the legs, etc. to get something to turn/push against. DC are also more painful when it comes to changing gloves.
One way to make the sleeves of a suit longer is to add rings in front (towards the hand) of zip seals. Most people have to shorten the arms if they add rings in front of zip seals to avoid the ring riding on the knuckles.
