I have an RC-2 and more recently, a Boomerang III. As far as drum patterns go, I am actually really enjoying NOT having any built into the 'rang. Sure having a bunch of built in patterns speeds things up, just pick one and start playing, but I found myself only using one or two of the available patterns on the RC-2 after a while, and it kind of made everything I played sound the same. Since I've been using the 'rang I've actually found myself learning more about drums because I regularly make up my own basic beats using various iPhone drum apps.
