Here is my comparison of the E30 M3 of Assetto Corsa and Gran Turismo Sport.
I used the Comfort Softs in GTS to get the lap as close as possible of Assetto Corsa's lap wherein I used the street tires.
Assetto felt understeery and rotating the car with throttle (throttle steering) was not easy. Whereas in GT Sport you have to take quite a different approach, it is very tail happy.
I like the GT Sport version more. A very fun and lively car!
I wonder which one is closer to real life?
