If / when I get a DS4 where the thumbstick rubber doesn't wear after a few months of low intensity use then I would be happy to vote DS4. But I am disappointed with having to get thumbstick covers which diminish the ergonomics of the thumbstick and thus make the controller less than what it should be.
Also I have no direct experience with the other controllers so I don't really qualify to vote.
