Google+ is new than Facebook Social networking website. So Google+ take a time to make his position in social networking website. Now Facebook is better against Google+.
According to my opinion, Facebook is the best social networking site compare to Google plus. Facebook has many Features and applications.
Facebook is the Best Portal but Google is Search Engine, So there is no compare between Facebook and Google, Google plus is a new Account for Us and we can use it as a Social Network as well.
I think Facebook is best for personal relationships and sharing, while Google+ is way better in terms of SEO and a good platform for companies.
Ofcourse Facebook as Google Plus is far behind. We are adapted to Facebook now. Also the average user time spend on Google Plus is very low.
Definitely Google+ I for one will never use Facebook to generate visitors!!! Even if i stand to loss possible income i refuse to you them Go Google+!!!!
As we all know Facebook have a big traffic instead of Google Plus that's why Facebook is one of the best social networking plate form.
