The power band is wider on the GT than my Roadster - and redline is higher (I think - I'm still in the break-in oil so no testing that yet). There are three drive modes which effect throttle mapping (four if you count the customized "driver" mode). Sport mode is very aggressive versus "Road" mode. The GT is also lighter, so the power feels different -- you can tell there is less mass to get moving. The Roadster seemed more torque-y in the lower revs than the GT, but that could just be the mass difference between the bikes. The GT has 6 gears versus 5 on the Roadster, so one would assume that the gears are not as tall on the GT? I don't know without doing a drive ratio comparison.
