Steve Smith seemed to be all about finesse, accents, etc. While Deen seems to be more about power, more of a rock style. I personally think Deen brings alot of energy on the drums to the classics. But overall, I'd have to vote for Steve Smith's drumming on the classics. It just seems more....dynamic. Deen as good as he is, just seems a tab bit less "loose" if that makes sense.
