if you break it down to wrestling then sure Hart was better than Triple H, and he was also better than Hulk Hogan too. but in terms of "professional wrestling" where it's a TV show and the wrestling is one of many things then Hart isn't anywhere close to Hogan.
I've personally never watched wresting to where I was focused on the level of "wrestling". it has always been a show to me.
Triple H had a perfect heel character. his was big and strong and bad. I never thought about him as putting on a great wrestling match because it wouldn't matter either way to me.
sure he was "booked" to win "X" number of championships, but I don't think that's a bad thing. it's a TV show. Undertaker has been "booked" to be undefeated at Wrestlemania. no difference.
I'm not saying I rank Bret low, I'm just saying everything included over the career I rank Triple H higher.
