Both are equally good
Thanks
If you want to drive more people to your website then FB and G+ are not the way to do it.
Those who use facebook and google and other SM sites will use these as a primary data source. They don't tend to go off site. Ergo, you cannot generally drive visitors to your site via SM. If you want visitors to your site you need to advertise or rank well for theings people are searching for.
I am personal like to Facebook because my mostly friends use this site but Google+ is best for SEO or site ranking.......
