heh. i know. i started a new game so i can experiment as a third file (in my first one i got yuffie and vincent to learn their ultimate limit breaks, and it was already too late for the others to learn theirs by then. in my second file i had barret and red learn theirs). In my third file i'm gonna have aeris, tifa, and cid learn theirs (since the moment you get cid all the way to aeris leaving ur party isn't too far of a gap in the game). I'm hoping to at least get Aeris to Planet Protector or Pulse of Life.
but yeah, Aeris is good when you have her. Sure, her attack sux totally when you first get her all the way half through the first disk, but after she gets Prism Staff and Aurora Rod she was stronger than Cloud! (at least, in my friend's file, which i played before i got the game myself. in that file i only got Aeris to Breath of Earth) it'll be a while before i get Great Gospel though...sigh.
