My favorite wrestlers are actually Taker and Sting, among others.

Sting - The guy's an Icon. Despite accomplishing everything there is to do in wrestling (besides join WWE which everyone other than him has eventually done at some point in time), he still competes. And despite his age, he's in pretty good to decent ring shape and moves around almost.....almost like a guy in their late 30's which is young for him considering how old he is now.

Taker - The most respected man in the business. Rumors suggest that he is willing to have The Streak end for the good of the WWE as he feels The Streak is getting too big. Gotta respect that he's willing to end one of things that contributes to his untouchable legacy for the good of the business. Don't think it should end though. He's put his body on the line and anyone in his condition would've retired long ago. He still puts on classic WM matches. If anything, the last 6 straight WM's have been proof of that. He has evolved and adapted to keep his gimmick fresh. Despite being stuck in his early days with limited guys like Kamala, Gonzalez, and Bundy, he's remained loyal and helped the WWE win the Monday Night Wars and go on to become what it is today - the biggest wrestling promotion in the world.
