All depends on the girl. Though, if you want to get technical about it, the majority of women prefer a taller man. It's a protection, comforting thing for us to have a taller man around to protect us and comfort us. It can also be a looks thing or a combination of both. All girls are different.
I'm 5'4", and I certainly like tall guys. I like guys who are shorter too, but tall and strong guys are pretty sexy. That means that when I hug or kiss them, they can wrap their arms around me and lift me off the ground...very sweet! :)
