The S04 is fantastic. I ditched my PSS for these tires due to road noise and balance issues on the front (defective front tires; my previous set of PSS had no balance issues, but were still somewhat noisy).

The S04 rides significantly quieter than the PSS and exhibits no perceptible loss in steering response or grip compared to the Michelins. The only advantage of the Michelins is supposedly longer tread life, but that's not a big consideration for me since I don't daily drive the Z4MC.

I think the S04s have been overshadowed by the heaps of praise the PSS has been (perhaps undeservingly so) receiving. I have been very happy with my S04s and would not hesitate to recommend them over the Michelins.
