I think its too close to call. The gixxer makes power earlier, wins the roll-ons in top gear (which may not matter to you), I think about 1000 rpms later for the 10R (Hp or torque peak).
The gixxer is more aerodynamic with a rider on it, per the wind tunnel results from the most recent Sport Rider.
The gixxer has been around for longer.
I think its too close to call, at this point get the one your heart says to get!
