OK but BA has infinitely more backstory and writing because it isn't limited to a few lines of dialogue from a stage where 90% of the lore is headcanoned by memes made up by the community.
I was part of the Touhou community I know how that shit worked. BA does similar things but there's way more actual meat to bounce headcanon and memes off of which is why it's so popular with the same crowd of artists that used to draw for Touhou.
