Crab is by far the best, as well as the most sane and stable on the show.
>Best looking, universally attractive
>Wouldn't technically just count as masturbation
>From the same universe, is human, not an impostor
>Looks both ways before crossing the street usually
>Doesn't pull a Caligula and declare herself a god before going full on murderous yandere over a love that was never even genuine, but simply an infatuation with the romanticism of knowing she'd never get him
>Doesn't run away from home and decide that if no one finds her she's gonna bring about a vampire zombie apocalypse
>Doesn't create TWO anomalies that first go around assaulting people, followed by repeated arson and possibly killing best girl
>Doesn't take out an anomaly that has been proven to attack people and try to use it again just because best girl isn't a carpet muncher
>Doesn't spend two years trying to feed a corpse and blaming Aririgi because he's not a mind reader.
>Doesn't exist as an M night Shyamalan twist who was so unstable she commits sudoku and doesn't even realize it, followed by going around as an apparition collecting another apparition's body parts
>Knows her own limits and when to ask for help, even if it's from someone she despises; resourceful
>Doesn't let the past stop her from pursuing her love for Koyomi in the present, doesn't even let gods stop her
TL;DR: Hitagi Senjougahara is best girl.
