Deviantart. Because they do not claim to own anything you upload. I do not know much about Myspace, but I have a burning hate towards Facebook, so in this case, due to the fact that "no news are good news", I will say Myspace.
I also have them both. I personally like facebook better then myspace. Facebook has more options and is alot more user friendly. Although the new facebook has taken some time to get used too. It is better in my opinion. Also it is not down as much as myspace
I don't like either. They are just boring, I mean yeah you can talk to people but not in real time, and whoopy you can copy a code to put on your profile, but seriously learn html, and css and make your own! I just had mine to test coding.
