The single greatest overall performer in the history of pro-wrestling in terms of skill , influence , star power , drawing ability , character and mic skills is The Nature Boy Ric Flair; this is universally agreed in the industry among majority of fans, peers, experts, promoters, managers and journalists.
When it comes to in-ring performances, no one will ever surpass Shawn Michaels his resume is akin to that of Sugar Ray Robinson; he was simply incredible and his greatness has been cemented across 2-3 era's.
After these two I could probably make a case for a number of wrestlers but Shawn and Ric's no.2 and no.1 ranking are not in doubt for me.
So I'd like to group a number of wrestlers in the no.3 spot which include Roddy Piper, Bruno Samartino , Dusty Rhodes , The Rock , Hulk Hogan , Bret Hart , Undertaker , John Cena , Stone Cold Steve Austin , Randy Savage , Sting , Lou Thez , Harley Race , Kurt Angle and Chris Jericho.
My personal favourites:
1. Shawn Michaels
2. AJ Styles / Kurt Angle / Chris Jericho
3. Undertaker / Kenta Kobashi / Jushin Thunder Liger/ Samoa Joe/ Brock Lesnar / Rey Mysterio / Eddie / Hollywood Hogan / Sting / Bret Hart / Goldberg / Randy Savage / The Rock / Austin / Kane / Daniel Bryan and probably many others
