The thing with social networks is that its heavily dependent on your friends and whether or not they are on that social network as well.
Google+ has a better layout than Facebook, no arguments there. Its also much simpler and easy to use. (the only little niggle i found about Google+ is that there's no obvious way to send basic personal messages, or wall posts)
That being said there's no one on Google+. And i don't see people leaving Facebook just to get a slightly better experience, its not a massive improvement over Facebook. So i guess most of us are stuck with Facebook :)
Its also funny how the new Facebook looks quite similar to Google+ lol,
