huh. out of all of them i'd say i prefer touhou, but only because i like bullet-hell games.
vocaloid = ehhh i don't have much of an opinion on them. i'd say I'm indifferent. the vocaloids can be used for some pretty decent songs though imo.
hetalia = never watched, only know it by the insane amount of times I've seen it referenced
Naruto = never watched, seemed too mainstream and from what i hear, has tons of filler. not too interested by it's premise.
touhou = ehhh not too interested. i'd only like the bullet hell aspect of it, but that'd be about it.
