That wheel perfectly matches the image on (SPOILER)the back of the robe worn by the Fayth which appears in the form of a young boy. That guy was once a Summoner of Zanarkand, I reckon that the Aeon Bahamut is an Aeon that was unique to him.
FFIX's Bahamut was quite impressive during FMVs, particularly the (SPOILER)raid on Brahne's fleet and the attack on Alexandria.
However, my favourite Bahamut for use in battle is the bog-standard Bahamut from FFVII. Brief and to the point, effective without all the fireworks.
