Let me add to what I said above, CM Punk to me has top 5-10 talent and skill set, as do Christian and Jericho, but I wouldn't call any of them an actual top 5-10 guy in any successful mainstream company.
Off the current roster or the roster from the past 2-3 years, I'd legit put their pure talent alone over many (Bryan's too right outside the cusp at 11 probably).
However if I was going off top 5-10 guys in recent years they would be the likes of Taker, HHH, Cena, Orton, Dave, Edge, HBK, Rey, Miz, Jeff Hardy, Big Show/Kane simply because at the end of the day it is a business. In that business you want guys with a high ceiling and who the casual fan and first timers will be attracted to, not just the loyalists or wrasslin faithfuls. Those guys have to be better protected and presented on TV because they are just bigger and better at putting asses in seats, getting viewers in front of the TV, and getting cash out of wallets.
It is like comparing Natalya, Beth, Mickie, Melina, and McCool to Trish and Lita. Yeah they are better in the ring and more naturally talented, but people don't give two squirts of piss about them in comparison.
Same goes for Hogan, Rock, and Austin in comparison to a number of people who could wrestle circles around them on their best days during their pushes.
