Best 3 at the moment would have to be , Anderson Silva, Jon Jones and GSP. Favourites are, BJ, Rampage and Sanchez
Bas Rutton, Sakuraba, Chuck Liddel Not sure if the other names mentioned here are because people only think of UFC when they answer this question, if so, check out Pride FC and Pancrase, old school style MMA
I was a massive Pride fan. I recently completed my DVD collection of all the events. Much preferred it to the UFC. It was amazing watching Cro-Cop, Wandy and Fedor etc in their prime. I just hope that given a few more years Dream can build itself up to what Pride was.
