10. Sheamus
9. Harley Race
8. Brock Lesnar
7. Owen Hart
6. Triple H
5. Macho Man Randy Savage
4. Bret Hart
3. Kurt Angle
2. Booker T
1. Stone Cold Steve Austin
Not a bad list, all things considered. You have to put Stone Cold at the number one, if only for the timeless promo he cut on Jake Roberts after winning. Booker T is the clear second, because of just how much mileage he actually got out of running the gimmick.
Otherwise, your mileage may vary.
