It depends on how you look at things. There's a case to be made for every era of wrestling. If you want to look at personal favorites then I'll give you my top ten. Oh, and by the way, sorry to burst your bubble but Shawn Michaels WAS NOT the goody goody you think he was. I can't say anything about 2002 on, but previous to his return in '02, Shawn Michaels was a basket case. He was on steroids just like just about everyone at that time, and he also loved dem little pills.

Anyhow, my top ten favorites all time:

1: Shawn Michaels... the greatest in-ring performer I've ever seen.
2: Randy Savage... great performer, great on the mic.
3: The Undertaker... Even when I was a youngster and hated wrestling because it was fake, THIS GUY brought me into the living room when I heard his music.
4: Ric Flair... Can't say enough about vintage Ric Flair.
5: Curt Hennig/Mr. Perfect... Not bad on the mic and a great mat technician.
6: Bret "Me Man" Hart... Even though he's his own biggest fan, I have much love for the man.
7: Owen Hart... Probably one of the more under-rated and underutilized talents in the history of the business...
8: Steve Austin... One of the greatest brawlers ever, yet when it came down to it, he was a great mat wrestler also.
9: Brian Pillman... See Owen Hart. There's no doubt in my mind that had he lived longer, he would have been WWF/E Champion multiple times.
10: CM Punk... If they'd keep him heel and release the muzzle, there is no telling what heights he could soar to. See the famous worked shoot and the summer and fall of 2011. Wildly popular.
