I think if you have a wheel you should have assetto corsa to go with it. I think you really have to have a wheel to appreciate driving sims properly. If your asking from the point of view of using it with a joypad then I don't know, I gave up on games like that a long time ago but comparing content there might be more enjoyment with a console like arcade game when playing with a joypad (although I know there are plenty of people playing AC with a joypad).
AC is the best driving game I've played, Kunos have somehow introduced the feeling of driving a car, you can actually feel what the car is doing rather than just relying on what you see in front of you.
You could get NetKar Pro and try that out, its very cheap now and is a representation of kunos way of doing things. I always thought it was a great sim it's a shame it never took off. If you like NetKar, you'll more than likely love Assetto Corsa.
