1. Bret Hart
2. Triple H
3. HBK
4. Angle
5. Ric Flair/Hogan
When I make this list I take into account wrestling ability/skills, as well as personality (mic skills, character) and longivity.
Personally, from what I've heard Hogan was never really an extremely talented wrestler in his younger days, but was more off an entertainer, so I can't put him up at the top. I have only seen Flair wrestler well past his prime, so he would probably be higher if I had witnessed him earlier. Rock left way too early, and I never ever really liked his gimick
In 5-7 years Triple H will be known as the greatest wrestler in history, with HBK as a close second depending on how long he remains in the industry. There is no arguing that Triple H has incredible wrestling ability (past and present), as well as one of the best characters in wrestling history & he will continue to carry the company in the future.
Angle is the best techinical wrestler ever, but I think his career will be cut short due to injuries.
As of now, the Hitman = "the best there was, the best there is, and the best there ever will be" BOTTOM LINE!!
