While I've played Crazy Taxi a few times, I don't have a strong attachment.
I'll say the font choice for the new one does seem to fit the name/theme better. First one makes me think of a racing game, second makes me think of taxis.
I also only just now realized the thing to the left on the original logo is supposed to be a C (for crazy taxi). The new one incorporating it as a replacement for the C in the name is a nice touch.
