Kirino is my one of my favorite anime girls of all time. Whether you like her personality or not her design is iconic. The other girls are all very forgettable in comparison to Kirino.
I originally didn't even like Ayase that much, but when pretty much every girl went out of their way to do something to really piss me off she quickly rose by process of elimination.
Saori was always top tier waifu material though.
Ayase > Saori> Kanako > Kuroneko >>>>>> Manami >>>>>>>>>Shit>>>>>>>>>>Kirino
There are tons of shows for kids, mascot characters, product advertisements, movies, and other such stuff that are also anime or use anime characters/art. While there is definitely a large otaku garbage demographic anime itself kind of reaches farther than that.
