Feedback and feel on the E90 M3 has always been good, not great. You cannot compare the hydraulic steering on the M3 to the pre-991 Porsche, Lotus, Sti or EVO. The M3 is overboosted, and lacks the true feedback through the fingers that define a great sports car. But it ain't bad.
However, compared to the C63, and I have driven every model year, the M3 steering is magnificent. The C63 steering is a numb piece of crap; like dialing and old rotary phone. No feel, huge play off center. This is particularly upsetting in a car with such outrageous hp and torque.
