It's hard to say, both have my 100% interest and I will have both pre-ordered and get them the day they come out.
FF XIII is by the main FF team and FF V XIII is by the Kingdom Hearts team. I love the main FF team, but I haven't played any KH game yet.
FF XIII has the composer Masashi Hamauzu, from FF VII: DoG, which I thought had ok music but some was good. FF V XIII has the composer Yoko Shimomura, who composed for Front Mission, Street Fighter 2, Live A Live, and other top games, I'm very impressed with her work.
The story and characters in both games seem ultimate, so that part may be the same.
Final Fantasy Versus XIII has the better composer but Final Fantasy XIII is from the main FF team, which I love, although maybe I'd love the KH team if I tried one of their games.
I'll lean slightly torward Final Fantasy XIII but only because it's the main game. I'm 100% interested in both games!
By the way, download the Manifold Irons track from Front Mission 1st(get the updated PS 1 version of the track not the old low quality Snes version!!), composed by Yoko Shimomura. Expect that type of high aggressive battle music in Final Fantasy Versus XIII! You can get that from zophar.net I think.
Anybody who listens to that track, tell me what you think of it please!
