Social Bookmarking is working fine for helping SEO. Everything social, these days, is helping alot.
As for if is better than Free Submission Directories?
Well these two are different. You cant exclude one against the other. Submitting your page to Directories, is useful and can give your webpage, some good points on authority, localization and many other aspects. But Directory Submission can't give as much traffic, as Social Bookmarking.
So go for both of them, this is my opinion.
