Vice Nebulosa... Nobody ever said it was quantity over quality. I believe (correct me if I'm wrong) what Wolf Kanno meant was that they are both amazing composers and it's hard to choose between them, but the fact is that Uematsu has written a lot more than Mitsuda.

You say Mitsuda's better from what you heard in the Chrono series. You have all the rights to do that, of course. But I think you're being a bit unfair judging Uematsu (and Mitsuda as well, for that matter) only on part of his work. The oldschool Fantasies hold his most memorable and classic tracks. Hell, IV's Theme of Love is even taught in music class in Japanese schools! I'm not even going to go into FFVI... Two words - opera scene. IMO, you can't really form an opinion on Uematsu's music without playing at least VI from the older games... Also worth mention is his extensive soundtrack for FFIX. So many tracks and so many incredible, memorable ones... You mentioned "mountains" and "valleys" - I agree for the most part. It just shouldn't be the bad tracks making the good tracks better. Nobuo has a lot of very tall "mountains" with few deep "valleys".

Some tracks from the Chrono series are amazing, but that does not make Yasunori Mitsuda the better composer. Uematsu has written a lot of equally (if not more) amazing soundtracks. When quality is similar, it's quantity that determines the verdict. I believe you're still unfamiliar with Uematsu's tallest "mountains"...
