I say Kevin Nash. Not so much in his last run, he seemed to struggle, maybe he wasn't used to going by a script. I just remember Nash in his nWo days, he always had something interesting to say. He was different from 'Taker and Kane in the way that he spoke with a sense of realism. While Hogan was the leader of the nWo, Hogan always said the same stuff, but Nash kept things interesting and his sheer size commanded your attention.
