What do you prefer: 2D or 3D platformers?

I want to say 3D but honestly, there really aren't that much 3D platformers that have what I'm looking for, I would say that fast-paced 3D platformers with intricate and acrobatic controls that lend themselves to find other paths to the goal or short-cuts using your own abilities are my favorites, but to my knowledge there's just 2 or 3 in existance so I dunno. (Mario Sunshine and the Sonic Adventure games, the Sonic parts.)
