MySpace vs. Facebook

I've been using MySpace and Facebook for awhile now. As some people know, I have only been on MySpace for a little while.
I can say that, as of right now, I like Facebook much better. It doesn't have garish advertisements, and also works more reliably. I've had a number of instances where various parts of MySpace did not work properly. I also get spam on MySpace. The only thing I get on Facebook is requests to join groups, but these appear to be legitimate groups and not webcam groups. The webcam group emails are really annoying. Lately MySpace has been assassinating the accounts of people who have been sending out spam, so that's good.
The other thing that I don't like about Myspace is how people use it as a subsititute for email. It's hard for me to keep track of MySpace emails because they don't stare me in the face like emails do. Plus, I sometimes like to flag messages for follow-up, and Myspace doesn't let me do that.
