its pretty good, i have the dfp and it rocks take a while to get used to because its not as easy to countersteer as the controller but you get used to it
A steering wheel is much like IRL but only if you can turn that feel like 900 degrees that's realistic. But second the car handeling is different from real life, it might be slight of but you can't get is, the tyres alone are very complex on how much grip you should have there are to many factors to take in to account. And between 3 and 4 well it is easy-er(don't know how to write it, I'm only Dutch ) to drift in 3 but a haven't really played 4 so I can't tell much about it
