I have the Conti Extreme DW on my E46 and although I think they handle great and are of good value, they have "softish" sidewalls and really feel lumpy until they get up to temp. Also, I think most tire shops have problems getting them properly balanced (they used a ton of weights) for that same reason - unless they have some magical way of heating them up first (maybe wait for summer?)
I have had no problems with the Pirelli PZero RFT's on my F10, but then again I only have 1,000 miles on them.
