I like them both.
Me too, but for different reasons.
Me too! : ),
I sort of agree with this assessment:
5 Reasons MST3K's Joel Is Better than Mike and 5 Reasons Mike Is Better than Joel*
I think Joel was droller in his delivery and Joel's lines, while I got most of the references, some of them were somewhat obscure unless you were really up on both pop culture and historical references going back way before the 1990's and as a result Tom Servo and Crow were left with the funniest jokes, as in the most accessible.
Mike's quips tended to be broader and focused more on the films and how bad they were instead of reaching for the more intellectual take on skewing pop culture and there was better banter between him and the bots.
But yes; they were both my favorites :)
