That Guy on 03 January 2009
from what I've heard, GH:WT has the best hardware (save for the foot pedal of the drums), whereas Rockband has better software.
Therefore, in a perfect world, you get GHWT AND RB2 then play RB2 with the GH instruments.
If that's not possible, then I say get RB1 on discount (its only 100 bucks now for some systems!), then get just the software for RB2. Then get GH3 on discount and use that guitar for the RB bass guitar.
