I've found that most people gain better accuracy with a wheel than a controller. At least that's what they've told me. As for going out and driving a car if you want a wheel. Well, not all of us can drive a car. Either due to cost, age, or location it's a silly recommendation to make. Finally, there is one car that doesn't use a wheel. It's a Nissan GTR R35 that uses a controller and it's just a promotion for Nissan so don't expect it to be repeated.
