None, they all fail. Since its literally impossible for a gacha to have a good story, the least they could do is to give us a decently cool and competent protagonist since its the character we control, and we have no choice in the matter. Who would want to control Wise or Aether instead of whatever other cool male is there in those games? At least the MC of FGO gets his dick wet with 90% of the females even if some of them don't fall for him, they still allow him to fuck them, and he has some cool moments.
If I had a gun to my head I would say the wuwa one though, since the entire story revolves around him, and he is shown to always go for the heart or the neck whenever he fights.
