I need to qualify this, 3D was really good, it was probably the most fun I had playing a kingdom hearts game (quite possibly the best music in a KH game as well), but BBS was the better game overall it had a solid story, a solid battlesystem, and significant replay value with 2 fairly difficult secret bosses. My biggest knock on 3D was the lack fo replay value compared to BBS (an arena and 2 secret bosses vs 1 secret boss, link portals, and dream eater stuff). If 3D gave me the same amount of replay value as BBS I would be calling 3D better.
