I have both. The mods in AC are good and you can take a drive in some historic cars etc...its fun.
ACC is just a whole new level. It is a very focused sim and as such is far more advanced. It runs a more advanced physics and aero model with data recieved from the actual manufacturers. Its the most advanced sim for GT3/4 cars available commercially. But, there is obviously more to it than this when it comes to choosing which is right for you.
The racing is always very close - the driver is always the factor in winning or losing, never the car, car setups are easier to understand and more in line with real life setup changes, and there is always good action online - remember the bit with all cars being extremely close (BoP).
