Although I've played them all, I've never finished any of them(and due to some problems with my *computer*, I only have a possible chance at FF5 Advance >.>), so I'm not sure I could make a fair judgejment. FF6 definetly had a good story, but for some reason I just didn't like the fighting style of the game, while it was sort of the other way around in FF5. Chrono Trigger has both, though, IMO, perfectly done, so I'd go with that. All that somewhat annoys me about that game is that the art for the characters look similar to DBZ, and that's not really a "fault".
