Gotta love holy wars...
After you're done with this one, try asking if you should use vim or emacs
Anyway, if you do decide to try Ubuntu, don't try KUbuntu (KDE version) - I've got it installed and I've come to regret it. It's nothing major, just all these small annoyances that *just* keep me from reinstalling the whole machine.
Anyway, good luck making your decision
