C6 Winter tyres

[jonas21]

So...given temperature drops and snow coming across europe...which winter tyres are you all using?
As i have the ceramic brakes i have to go for 20". That said i just see 2 tyre options:
1. Pirelli Sottozero Series 2 275/35 R20 102W
2. Dunlop SP Winter Sport 3D RO1 MFS 275/35 102W

I have read various test reports (altho none of them compares these both directly) and it appears in smaller dimensions (225) the Dunlop is actually a leap ahead of pirelli. The dunlop's are a bit cheaper but apparently better. For summer tyres it seems just the opposite.
So...which ones are you using?
