Differences in mass-inertia response.
Aerodynamic control response, amount of rudder required as speed decreases. Roll-Yaw ratio, pitch rate and pitch damping; ground effect (higher in T7).
Simulators may not provide a realistic side force - lateral acceleration, thus essential body feedback is lacking. This can be a big issue for aircraft with lateral directional characteristics where fine control depends on good feedback.
Fly as per the book to provide a datum, then with experience evaluate each of the above factors to optimise technique.
Attempting to use a previous type as a datum can be confusing. All aircraft fly, and can be controlled in a similar manner, but similar is not always very close to 'the same as'.
