Gamma Neon Tac is more tacky than the supreme.
It's even written on the box: Supreme 3/5, Neon Tac 4/5.
Too bad that gamma has only these stupid neon colors, but Neon Tac is the by far the tackiest grip.
Wilson Profile is also very tacky, but not with very dry hands. I have notice that with a bit wet hand the "profile" sticks more on the hand.
