Incidentally, my votes are as follows:
Angle, one of the greatest technical wrestlers of all time and an absolute genius on the mic.
CM Punk - the future of the business. The sky's the limit for him. Had some epic battles with Samoa Joe in ROH, and at WrestleMania 23 among 83,000 people there were signs saying "I'm here for CM Punk", and "Punk is God", before he'd even won his first title in WWE. A supreme talent, compared to a guy whose entire moveset is composed of chinlocks.
Edge, one of the greatest tag team wrestlers of all time and a superb mic worker, plus he's put his body on the line more than most for the business and can wrestle almost any style of match to a high standard. Shamrock was good, but Edge is Hall of Fame material.
Bret Hart - in terms of quality there's not much to separate them, but Hart didn't murder his family so I'm gonna go for him.
