The DWS06s are 18" and the S-04's are 19", and the Bridgestone sidewalls seem to have a lot less flex, so there is a slightly better ride on the All-Seasons due to that, The Bridgestones are almost worn out after about 22-24k, but I've gotten great life out of them by rotating them every 3-5k and keeping the pressure checked.
I've only had the Contis for one winter and they haven't shown much wear at all yet.

Just installed Michelin Pilot Sport 4S. Brand new tire for Michelin. Haven't pushed the traction yet, but ride quality and noise is very good. Bstone S04s are good tires...I've had them on my M3, but they are heavy, almost 5 lbs heavier than some others.

Replaced stock Contis after about 7.5k miles...they were done (and not driven hard). Great summer handling.

Mounted in autumn, DWS 06 worked well in snow (NOT as good as real; snows of course but still good enough in tough conditions...I live in the country and have a long, steep driveway) thanks to Quattro) ...but they are/were nearly new.

Dry and wet road summer handling is decent so far...but not as good as the summer Contis were (of course). DWS 06 sidewall feels softer, but gives nice ride and noise. Tire wear TBD but has to be better than the summer Contis it came with. (but some reviews say they wear too fast..). Time will tell I am not an all out driver these days...but I plan to I will probably install winter tires next year after they are worn some and may get 3 summers out of them.

I echo the previous reviews that DWS is good tire if winter matters (especially supplemented by Quattro) and it is a good value as well.
