it depends, if you want back-links from google G+ is good, but if you want traffic Twitter is good.

goole looks very nice and because it is google it will have alot of power over seo if used right but does not have enough users yet and twitter has most people using it

Twitter is best for getting best audience on your website.

The news that Google Plus (Google+) is now the 2nd largest social network, surpassing Twitter and YouTube, seemed to shock a lot of social media marketers this past week. Reaction to the news bordered on anger in some quarters as Twitter advocates were quick to extol the virtue of the micro-blogging platform.

Both are best and Beneficial for increase traffic rank on your site.

Google+ is the king of all networking sites and this is the best social networking sites

Google+ is better because this is Google+'s product and it directly connected to Google

It is difficult to make up your mind as to which is the best suited choice for website promotion. Twitter is suited for building connections.

Google plus for sure. Twitter and Facebook both are NOFOLLOW when it comes to Google.

Google+ is absolutely better than twitter because it provides high quality do follow link for your website, if you are taking it for seo purpose otherwise twitter is best.
Thanks.

I like Twitter most, but Google+ is something newer and better than Twitter

i like google more but twitter has so many more users

both are the best sites

Twitter has more active users then Google+ but Google has some SEO advantages

I'm an ardent Twitter fan - most Google+ profiles are pretty inactive (at least those I've seen)

Now a days google+ because its a part of google and google always support it.

Twitter is best

google + is more predominant in search engine.

Google+ always better than twitter ..You cant do Business listening and map listening with Twitter
