I had a set of Blizzaks on a 2001 Nissan Maxima. At the point where they has about 1/4 of the tread left, I rolled the dice on brand new all seasons. I tried getting through a snow storm, got stuck and had to resort to a set of cable chains I had in the trunk as a worst case back up plan. Got the car into the garage, changed out to the mostly worn Bliazzaks, and they went through the snow eezy peezy. So from my experience, even worn out Blizzaks are far superior to any all season tire, even when new. YMMV. I have had nearly every snow tire available the last 20 years on my car, and for mostly highway driving with snow (and more importantly, ice) traction, Michelin X3s are the way to go. I give Blizzaks an edge for traction, but they do wear faster and feel "mushier". Contis are ok but wear as quick or quicker than Blizzaks. Dunlops..."meh". Studs get the tips broken off pretty easily, and without the you give away ice traction. If ice is your concern, go with Blizzaks. And no, I don;t have experience with Hakkis, I stick with brands that are more widely available (try getting a replacement snow tire in February LOL)
