I've got LOK Bogie palmswells on a P01 and like them very much. I have Cool Hands on a Rami, and like them too. I've had VZs on 1911s and they've been great as well.
While it's completely subjective, and not apples to apples as they are very different guns, I'd say I prefer the Bogies (most grippy), then the Cool Hands (on appearance) then the VZs (which are still excellent).
