Back in say, 2000, when they'd both retired (Shawn temporarily), the debate would probably be quite even, possibly in favour of Bret. Then Shawn came back and put in another 8 years of work, culminating in arguably the two greatest WrestleMania matches in history. Shawn was regarded as one of the best when he retired in 1998, but today it seems widely accepted that Shawn is the single greatest ever, while Bret has settled into that "one of the best" category.
Does anyone here and now, in 2014, think Bret was the better of the two? And why?
Remember it's all opinion, people...
Yes, I do think Bret was better. I do not think it's fair to say Shawn is better because he had a longer career. Bret suffered a serious injury due to another wrestler's sloppiness that ended his career prematurely, and there's nothing he could do about that.
Shawn was fortunately able to recover from his serious back injury and extend his career.
But I believe you rank guys by how they were at their absolute best. I think Bret was better at his peak. He had much better championship runs, and personally I preferred the storytelling of his matches(slightly) over Shawn's.
Shawn put on phenomenal matches too, no question.
I also think Bret's feuds were more consistently great. Shawn had some great ones with the right opponents(Jericho, HHH, Razor), but Bret seemed to have more, with more opponents. I feel the same way match-wise.
If you compare the phases of their respective careers......Hart Foundation >>>Rockers. Bret's midcard IC days > Shawn's midcard IC days(close though). And Bret's WWF title days/top of the card days >> Shawn's title runs/top of the card days.
Now Shawn had a phenomenal late career run where he wasn't winning titles, but was usually in top matches. Unfortunately Bret never really got to have that phase of his career due to the Screwjob situation, WCW, and then the injury. I would've LOVED to see Bret Hart as a veteran in early-mid 2000's WWE taking on Chris Jericho, Chris Benoit, Kurt Angle, Eddie Guerrero, Rob Van Damn, HHH, Brock Lesnar, etc. So Shawn has that edge on him, and given that that phase happened recently, it's fresh in people's minds.
