Is the fb_graph gem better?
It seems to be newer, but the facebooker has a lot more people using.

Update:
I looked into koala, and it seems it is a good choice as well.

I also figure out that fb_graph is different than fbgraph. This is the right one:
http://github.com/nov/fb_graph
And there is a new facebooker, that uses that Open Graph API, but it doesnt look as mature as the others:
I've been using Koala and have been very happy. It's very low level - meaning no abstractions that try to do stuff for you. The graph API is very straightforward, so this the best approach.
I ended up using Koala. It seems to be the best choice now. Facebooker2 is still very early stage, and Koala does a great job wrapping everything.
Don't get confused! Facebooker is for the old FB API!
The original Facebooker gem was split into two pieces for the new api - Facebooker2 for front-end helpers/auth and Mogli for back-end open graph api calls. Both are managed by the same person who did the original Facebooker gem - mike mangino - who does a great job of supporting both. Mogli is most directly comparable to Koala.
So far, I'm a big fan of koala, but I've not tried fb_graph. I did post a comparison of a few facebook gems here: http://jeffdeville.com/minifb-vs-koala-vs-mogli-facebook-graph-api-r
