I used to really like Myspace because of the personalization and everything I could do.
Although I do prefer facebook now, subtler adverts, not constantly telling me of mafia world etc, I don't like the lack of privacy, i.e. you can't write practically anything without it beig posted everywhere (with the exception of private messages) and also if someone wants to be my friend and I don't recognize their name, I can't view their profile, I just have to assume I know them or ignore them.
So basically, if I could have myspace layout page (with the personalization) and then the facebook layout, that'd be great.
I don't use myspace very much now, but I still check it.
