Nope! Still Kirk, open and shut. After watching Jim Carey do a Kirk immitation... Picard rules, but "Spoocckkk... HE's not... ME!"
Literally, it all comes down to acting. I could watch Kirk all day... and the fact that the stories are decent, well, that's icing on the cake
Picard... excelled at the usual fare and was quite convincing, but never quite got the whole "passion" (I'm really pissed off / we're all gonna die / I'm gonna mutilate you / etc) thing down. Not in a convincing manner, at least... but he tried, and it didn't work. Kirk, OTOH, failed worse - but it didn't matter - the audience had already "suspended belief" when it came to his responses, so it worked perfectly!
Granted, I'm a lover of MST3k as well, so my opinions may need to be qualified.
Ah frick. The kitten is trying to help me type.
