I'm only half way through my first time in B2, but so far I mostly prefer the new gyms. The only one I didn't care for much was Roxie's gym, since it wasn't really a gym. It was more like I just tromped up there onto the stage in the middle of a show and interrupted for a battle. It just seemed weird. Burgh's remodel was pretty good, and I loved both Elesa's and Clay's - Elesa's for the ambience and Clay's for the puzzle.
