I'm thinking about it. I just need to know which has the best instruments, this or guitar hero.

Got to play with the new instruments for a short time at walmart, and they are 10000x improved. I mainly play Guitar, and I'll say that I think I like the RB2 Guitar better than the GH3 Les Paul, and that's saying something. The drums seemed to have better rebound, were quieter, and the kick pedal seemed better.
