Do you mean Vixskin?
If so, then there is absolutely no comparison between the 2. Vixskin is silicone (safety rating of 10) and Cyberskin is a PVC compound (safety rating of 2). I would never get a toy made of Cyberskin (safety issues, smell, won't last long, etc), but I am a HUGE fan of Vixskin. It's a wonderful dual density silicone that is safe and feels great.
