I must admit, I didnt try the other available sponges.... but with Charisma sponge, this rubber really gives me a great sensation of grabbing the ball, then placing anywhere I want it with superior torque when spinning/looping. When hitting, it sinks in for an instant, then releases with just enough spin so that it seems to drop in now matter how hard I swing. It is just shy of being sticky... so great for serves and pushes too. My new favorite.
