SURBLs will only come into play if SpamAssassin is turned on. They're part of SA. They filter out emails that contain spammy urls in the body of the message.
RBLs check the sender's IP address. Messages are rejected before being transmitted, so they save bandwith and subsequent processing (queueing and scanning). >From my observation (not statistical) on 3 servers (2 small, 1 very large), I would guess that RBLs reject 60-75% of all attempted deliveries. This is using the RBLs recommended on the wiki. I'm not aware of any false positives from these RBLs.
