Don't ask that. There are too many opposing opinions, especially on this board. Both have totally dominated their weight class, and I mean in a complete degree. The only real advantage that Fedor has is that he has been dominating longer. Fedor has been dominating the HW class for going on eight years now, and Anderson has been killing folks for about three. Fedor has only one loss, due to a bad cut in 2001, and Anderson has three losses, two submissions and one for using an illegal upkick against Okami. Anderson has fought the best there currently is at middleweight, but there are people who point to Fedor's lack of wins against Coture and Josh Barnett as holes in his dominance. Fedor has, though, defeated Big Nog twice, the interem UFC champ who I personally think would take Randy pretty handily and has beaten Josh as well. And no one in their correct mind thinks that Fedor wouldn't manhandle Brock, who will fight Randy in november, especially because he usually fought some Japanese giant freak show and won every New Years Eve for a while.
