I have Michelin Arctic Alpines, they suck in fresh deep snow, they don't have aggressive treads as Bridgestone Blizzak WS-50's, they have thousands of tiny but deep grooves instead, they do relative well on packed snow and ice because these numerous tiny grooves can bite into hard surface, but they are useless in deep snow, they do good on highway also. Take a look at the tread pattern of these two tires, you can see the huge difference.
Blizzaks are very soft and noisy, they are more like dedicated snow tires. As I am in Canada, next time I will go with Blizzaks.

Still missing the days with the Benz, it kept me busy.
