In my playthrough, I didn't use Snow very much. However, next time I play the game, I plan to use the characters that didn't make it into my battle party very often. I think it'll add a pretty decent challenge for me, since I was another one of those people who went the Lightning/Fang/Hope route.

As for Snow as a character, he's alright. A bit of a showboat, but I suppose that's just part of his charm.
