I don't find to be any different, but I must say that I do prefer a girl with longer hair most of the time. It's just a matter of is the girl taking care of her appearance in general. Hair style shouldn't really effect that, but some dudes just prefer a girl with shorter hair. Just personal preferences.
I would not find a girl with hair like that more classy, or mature than a girl with longer (or shorter) hair; those factors are determined by her actions, and the way she dresses. I always find long, maintained hair very attractive, and I usually dislike anything that is shorter than about chest length, but there are always A FEW exceptions to this. Every guy I know likes girls with long hair.
I'm personally not a fan of short hair. Shoulder length or longer is much prettier in my opinion. I like it when girls who have long hair out they're hair in a pony tail. I think that's a very cute look. But maybe I'm a weirdo lol
