I never touched HSR and I firmly believe with every fiber of my being that it easily mogs Genshin's for the single fact that not only Genshin has no story whatsoever, but the deeper they go the more dumb, bland and convoluted it becomes.
Genshin remaining (and only) silver lining is that it's a proper game (while being an insultingly awful gacha) while our sister gachas are shit games but extremely well-done gachas.
So yeah, Wei massive hater boner for us isn't exactly a mistery, it's a simple matter of priorities.
