4 because I made some pretty good experiences with alternative Girls (Goth/Emo/Punk).
Some off them might be immature and are just trying to provoke but from what I experienced this is just a very small part of this group.
Most alternative girls are very interesting people with an interesting personality.
Another plus is that the emo/goth-girls I meet are a lot less shallow than some "normal girls" (I'm not saying that every normal girl is shallow but there are a few that are, while it's hard to find emo/goth-girls that are)
4 probably for me. I'm just attracted to girls with emo style looks, I personally like girls with piercings and dyed shorthair more than a girl with a more popular look (long untreated hair and ordinary clothes) amongst the female public.
