Both go too far in their own directions. AC 1 is somewhere in between the two, having slides that can be saved, but with more effort required than in AMS2. That's the standard to shoot for...except for the curb behavior. Some cars with TC in AMS2 have that kind of near-perfect handling. But if you cut off the TC completely, they're just too stable. If you cut off the TC in ACC, they have the unrealistic "on-and-off" instability similar to AMS1 and rF2. ACC also seems to have that problem, to a lesser degree, in the rain.
