The big difference between the two is that rFacebook is a giant hack of a library and even the guy that made it realizes this (and thus, doesn't even maintain it) and Facebooker is a set of Ruby objects that makes it so you don't even have to think about the API (not really). rFacebooker is very php-ish (which means some people really like it, the friends for sale guys, for example). The Facebooker library also has fixes to make RESTful routes work, and there's related library that makes asynchronous requests stupid easy (FacebookerMQ).
