Watching Eden's summon animation is indeed hilarious, is it the longest one in the series? It beats KOTR surely. At least you can Boost to max without worrying!
I forget if Seabass already knows- some GFs don't like each other and their compatibility with the player will go down if you use the summon they don't like. The opposition is generally pretty natural to figure out but here's a list anyway:
Shiva-Ifrit, Quezacotl-Leviathan, Siren-Carbuncle, Brothers-Pandemona, Alexander-the other one you don't have yet (not Tonberry).
They also have different base compatibilities with each character but this doesn't affect things very much.
Again quick word on the other GF left after Tonberry- you can figure it out yourself if you've been collecting Occult Fan magazines but otherwise you might want some board help with that one. Also involves a bit of unpleasant grinding iirc.
