Played BA for like 2 years, started weeb mlp a with the recent release of global. Just making my bias clear.
BAs got the less paywalled gacha system, wider girl variety (both in bodytypes and personalities), better art imo, more fanservice, and a much more interesting story imo.
Umas got budget, just compare their animes to BAs, it's gameplay is more indepth than what you'll be doing in BA (mostly autorunning to grinding mats for raids).
Oh and boths soundtracks are pretty top notch too.
