Facebook Ads has traction as a serious, targeted ad platform. You can drill incredibly far with your demographics and interest groups and still get a very chunky network reach.

By and large, networks are the same but they're completely different at the same. Places like The Deck or BuySellAds you'll more than likely see a lot of blog traffic coming in but you can also expect high bounce rates (this I say from experience). Google AdNetwork/Doubleclick you might get a completely different number, with more varied interests/keyword results, but spend longer time on the site.

I've got a couple of PDFs I will give you that goes into pretty deep detail about FB Ads in specific.
