I think it's between Cm punk, Daniel Bryan, Austin Aries, Jeff Hardy, Dolgh Ziggler, and Booby Roode. My personal favorite is Dolgh Ziggler as he has so much potential to being the face of the wwe. I think they should turn him face.

It;s been a long time since I can remember a wrestler having THAT much amount of heat in such a short amount of time.
He's also a terrific wrestler, amazing on the mic, and is willing to put over new talent.
After that (for me), it would be between Aries and Bryan. If Aries was still World Champion, and if Bryan was in the WWE/WHC picture, I think they could give Punk a run for his money, but for now he is pretty much untouchable.
