For me hands down the M Sport. I really like the thicker rim and also the leather is much softer. To be honest, I do not like the feel of the Sport wheel, the leather is too coarse IMHO. When I rodered the car the M Sport was not available and did not want to wait for 5 months...now I am looking to replace it with the M Sport. I had the M Sport in my Z4 (retrofitted by myself) and it was so much better!
