Question

I have a Wii, and I am torn between getting EITHER Guitar Hero World Tour, OR Rock Band . Which one is better?
OK, so I have a Wii, and I was wondering which one is better, in terms of song list, features, etc. Also, it matters that it is on Wii. Like, what about Guitar Hero is better than Rock Band, and vice versa. And about the DLC, I know GH will have it, will Rock Band? If it does, will you be able to get all of the songs from Rock Band for , too?

Answer
