I went from an E39 (rwd obviously) to an xDrive F30. Now it's not an apples to apples comparison because of the different models but there are some differences.
The steering in the E39 would return to center much better than on the F30. But now that I think about it, it could be due to the EPS vs hydraulic steering. Overall, the differences are not something you will feel in your daily drive, more on the track.
I can still kick out the tail with the xDrive and DSC off and that's all I really care about frankly. In winter on snow, 4 wheel drifts are much better controlled than RWD if you want to have fun
