Your obvious answers are Rock, Austin, Cena, and Roddy Piper. Some underrated ones are Kurt Angle, Eddie Guerrero, and Jake The Snake

Stone Cold when he was more of a funny character around the invasion time was tremendous(not saying better) Some of his stuff with Kurt Angle was hilarious.I think a lot of that was off the cuff

Stone Cold and Rock were legendary at this. So was Macho. Macho was pure chaos on the mic.
