Yes, DWS can take Snow very easily, better then Perilli Zero Nero.
Perilli can take snow too but less road noise, DWS are little better in Snow but more noisy as compare to Perilli
Now winter Blizzaks are much better in Snow since they are Winter Tires but they come with a cost of more road noise when no snow on the roads but still Winter weather.

If I live in some Hilly area like Colorado and have to face Snow every day then Iwill go with dedicated Winter tires like Blizzaks, If I live in non hilly area and Snow is occasional like 2-3 days out of 7 day week then I can stick with DWS or even Perilli.
