Superskin is the best feeling, most realistic. But, I do not care to much for the lack of tightness. I feel the need to use c-rings and such to make them tighter, it helps to feel the textures. Also, you are not 'supposed' to use soap to clean it, and they take a long time to dry. (Although I have had no problems using Climax burst)
Tenga's TPR is much stronger and feels tighter, you can not only clean it easier you can clean it with soap. It drys faster due to the design as well.
My Flip Hole Black is still my favorite and will be until I try one of the Fleshlight Can strokers. Even then I am not sure it will beat out the Tenga.
