I used to like watching Ken Shamrock who was always introduced as 'The Most Dangerous Man on the Planet'. He is far and away the best fighter professional wrestling has ever had. In a real match with no acting my money would be on him. I used to watch him when he fought in the Octagon and the only man back then who beat him when Shamrock was in his prime was the legendary Royce Gracie.
Entertainment wise I think the best WWE wrestler is Torrie Wilson, I could watch her all day and I like watching that made move Lita does were she graps hold of the other wrestler around the head with her legs and sends them flying all over the place.
