Rock Band. Definitely. They're busting out new GH games way too quick. GH is still awesome, but not as awesome as it was. RB was the first one with full band support, yes, but also, it has better setlists, gigantor globs of DLC of like any genre of music, from Brad Paisley to Children of Bodom, and is always coming out with new content. Also, I have all my GH/RB games for my Wii, and I can never find opponents or bandmates on GH, but I always can find someone to play with co-op on RB2 or Beatles RB.
