I don't think that facebook or twitter is a part of seo, just to correct you these are the part of SMO, called ,social media marketing.
According to me both are different , so you should not compare both of them but according to me i will definitely vote for the facebook as its very good
My friend told me that twitter is kind of boring, all you can do there is just following, tweeting or whatever (I am not into twitter though). I guess my answer would be facebook. You can get a chance by doing a business on facebook too.
Not neccesarily, Twitter can start a conversation with someone you might do business with later on down the road.
They are working for different kind of social status and scope. Twitter is much wide while facebook is professional
Of course facebook is better, being a more "hands on" experience all around. Twitter is practical, but short and detached.
In my point of view facebook is better than twitter.. We will get more business through facebook only..
facebook is the best one and much better from Twitter. We dont have to follow others like twitter.. FB works as a open and for the closed as well . i am with Facebook as its social network and easiest from Twitter
Both Facebook as well as twitter both are equally useful to SEO as far as their submission types are concern. Twitter is good for micro blogging while Facebook takes his lead in Social bookmarking
