Similar experience I have learnt incase of Sprinter (18 inches tyre) and GD110 (17 inches tyre).
I had a discussion with a rider who owns Sprinter and GD110. He told me GD has better acceleration, road grip more or less same, Sprinter has longer gear stretch and top speed also. To keep top speed factor simple he was like k reaching 100 - 110 km/h on Sprinter was easier than the GD. But GD clearly outclassed Sprinter in acceleration.
