I'm going with the Rock. The ONLY thing Brock has over the Rock is the victory in the ONE singles match they had. The victory loses its luster for a couple reasons. Number one, there was heavy interference throughout the match from Paul Heyman. There was one point where Brock had his hand up ready to tap to the sharpshooter and Heyman got up on the apron distracting the ref. There was another point where he threw Brock a chair that Lesnar used on the Rock, so the victory wasn't exactly clean. Secondly, Brock won the match and the title because The Rock was leaving to make a movie. Rock was gone for 5 months after this match so obviously he wasn't going to be booked to win. When it comes down to it The Rock is better then Brock in every facet of wrestling. He is a bigger draw, more popular, better as a face, better as a heel, he has had the better career, he has beaten more big names, he has sustained success over a longer period of time both overall and in successive years, he is better in the ring, and he takes a giant diarrhea shit all over Brock when it comes to mic work. I'd also like to point out that RVD is 1-0 against Steve Austin in singles matches, so if Brock beats Rock because of their Summerslam match does that mean you would also vote RVD over Austin?
