If you want to rock out and shred like Vai, Van Halen and Satriani, GH offers a more score-focused game and a greater challenge. If you want to get closer to the real band experience, Rock Band 2 has it down. Of course, GHWT now enables you to make your own music, but to my mind Rock Band 2's stronger online modes and authentic feel make up for that. In other words, it depends on what you're looking for. Buy either game and you'll have a great time playing it, but in the end this choice has to be personal. If TR had to plump for just one of these titles, they'd be splashing out their cash on Rock Band 2.
