I have tried some more expensive ring type sound cotrol, and some of these. These are slightly more slippery and thinner, but I haven't noticed why it would be worse/better.
The only problem with all the rings I've noticed is, if you accidentally make a sharp bend with them, it's really hard to get the wrinkle out!
After testing some gel type solutions, I personally prefer gel type sound control, but if a ring control type is your thing, this works just as well as others of the type I've tried.
