Well I put down Tito Ortiz but I honestly couldn't decide who is. I like many different fighters (I only watch UFC btw and have only started watching it.)
Mac from the Ultimate Fighter is good. I liked him on the show. Matt Hughes is good as well. Saw him a while back before I got into UFC like I am now.
Tito, Chuck Liddel, Rampage, Guida, Huerta, Mirko Crocop, and a few others (there's another I wanted to add to the list... Oh Forrest Griffin! I think that's his name lol
But yeah I just got into watching UFC. So I'm a bit of a newb on this right now
