One thing I've noticed with F5, more so than with any other console sim, is that it can punish you for creating sudden weight shifts with you car. As long as you focus on trying to keep your car flat and clean you get rewarded. And I mean by easing slightly into the brakes to reach max brake force, rather than a quick brake which a lot of other games let you get away with.
Not sure if other games apply breaking and steering force along a curve to prevent players from creating herky jerky movements, or if roll and snap are more directly "simulated" now.
I cant really say about Gran Turismo when playing with the DS3 but I am sure what you describe is strongly present in GT with my G25 steering wheel and everything in the simulation settings twicked for max realism
