Flown all three - I'd place the 'Dog first because it still felt and smelt like a military trainer, whilst the T67 rolled like a sloth on Valium....the Tutor feels half way between, and also benefits from a judicious boot of rudder - just not as much as the Firefly. I didn't fly the T67 M260, and appreciate the grunt was probably nice, but it wouldn't have improved roll rate. Only flew the Chipmunk a couple of times but if you could bottle nostalgia.....
