It is probably best on the SNES. The PS1 was changed a little. It spoiled some of the surprises or plot twists, for me even though I already knew, by the way they redid some of the writting of the story. The GBA always chops up and shortens any ported RPGs for some reason, one example was Lunar Legend. I haven't had the opportunity to play the DS version yet.
I liked FFX. And I really like the way they did FFXII. I am in-process of playing it periodically. I like the way it feels massively big when going through the city.
