I found Biggs and Wedge as more of a plucky comic releif slthough they were fun as well. I've got more too i'm sure, but it's late and i can't think straight at the moment.
i liked the lvl 100 ruby dragons before bahamut, bahamut is my favorite boss the lvl 100 rubys just heal me before i fight XD (elemental resistance roks!!!)
ummmmmm well id say the fight against tiamat was cool but my fav fight was against seifer in the lunatic pandora when odin gets kills. the limit he uses (i cant think whats its called) looked awesome and i thought the whole thing with guilgamesh coming into the battle was cool......i mean his second appearence since ff5
and the diablos fight was fun coz of the cast demi and he cast curga back tht was awesome
My favourite boss would probably be The very last one before you beat the game as when you beat the game you get the awesome credits and it gives a great sence acheivment afterwards.
