Rockband.. Duh! Just for the fact it does more and the wife will sing.. She won't play GH but she will play KR.. So.. That is a bonus for me. Also like I.B. said.. has more replayability and will likely not dissapoint with the DLC.
And Scorehero peeps are sheep. GH3 is the usurper.. Not RB. They are turning their backs on the very devs that gave them what they have held dear. If Jesus came back and changed his name to Pedro and created a religion called Pedroism, But was still ultimately the same person preaching the same things, only much better than before, Would Christians bad mouth him and say he sucks?
I think they would.
