Animation wise, BDD has some nice points, like the chemical structures and the quantum physics in the background, and it certainly is nice and fluid, a good job. But MSF has spunk and IS for sure better choreographed.
As for the music, MSF FTW! Now if this were between Motteke Sailor Fuku and Hare Hare Yukai, I'd have to vote the latter. But since it isn't, I reiterate: Motteke Sailor Fuku FTW
