My vote is for Dedicated Snows for winter, Dedicated Summer's in the Summer.
Really who cars what the car looks like in the Winter and even the worst Dedicated Snow will out perform the best All Season in Snow.
Summer tires offer a level of steering and handling response that can't be matched even by the best all season.
Just my 2 cents.
