I confirm.
When I had 2 Winter tires fitted, a snowstorm was building. My 2WD SDrive was fishtailing all over the mechanic's parking lot.
I pulled away one hour later with my 2 Nokian, and it was day and night.
Even on the steep hill to my place, I deliberately stopped the car, and it hauled back up again with hardly any wheel spin.
2WD + Winter tires + DTC gets you our of most situations in my opinion, especially in an urban environment.
