I have the discoverer's but put them on in the spring so can't answer your question just yet. Price difference was huge compared to michelins, but compared to the tread pattern on my old mich's they look pretty good, better siping etc. I guess it'll come down to how soft the compound is in extreme cold. Bottom line, drive to the conditions and don't be one those a-holes that figure because they have awd they are invincible.
