In addition, there aren't 3 toms on the RB setup, only 2. I've never seen the green pad used as a tom (although I only have around 30 DLC songs), and the fills only use it as a crash. It is possible that the red pad is occasionally used as a tom, though. It seems like "Run to the Hills" does this. The vast majority of the time you have one snare, a hi-hat, one tom, and the crash. In the fills you get the snare, two toms, and crash. So the GHWT setup would still give you a snare, hit-hat, crash, and two toms all the time, in addition to the slightly better placement.
At least RB2 is fixing this with the cymbal addons and the Ion kit, although that doesn't do anything for the limitations of only 4 pads during the charted portions of the song. I think that's mainly the poor positioning, since they change which drum the pad equates to often enough to get you a decent experience.
