I really liked Chris Benoit, before he did what he did. In the ring, I think he was really second to none.
Best ever though? It's between Ric Flair, Kenta Kobashi and Terry Funk, for me. I've been lucky enough to meet all 3 of those men over the last decade, too. In fact, I've met hundreds of wrestlers, including a few of the bigger names of the 1980's / 90's. Ultimate Warrior, Bret Hart, Roddy Piper and Ted DiBiase Sr. to name just a few.
