Still now facebook Definitely Best and Google+1 is not a social networking site. Its a social layer to handle the communication and interaction
Google + is a new technique evolved by Google. I am not aware about this technique so far. can any one suggest me that is it beneficial for SEO? If yes then how?
I think the Google + is good just because it gives the opportunity to add the friends, family members and the classmates are in different circles...!
It is too early to compare Google+ with Facebook at the moment. FB is a giant and Google is a giant in its own way. To compare the two you would need a common ground so Google has now come up with it's +, until the whole version is released it will be difficult to say anything.
It is video chat feature of Google plus that allows group video chat and you can see youtube videos together with your friends. Facebook also enable its video chatting but lacking by this much from Googl'e
