depending on how many miles you drive and how much it snows, blizzaks are fantastic. Had them on both my Impala SS and 94 trans am and never had a problem in any snow. (used 4 per car not just two on the rear). They werent very good in dry conditions as the tread blocks are soft so you cant drive agressively but you wont ever get stuck in snow and ice. I think you will find this with all winter=only tires.
Id think the new goodyear assurance triple=tread might be a good winter tire. Low speed rating TR which is only to 118mph but how fast are you really going to go in winter right?
Nokian makes a good winter tire too I think.
just some ideas off the top of my head.
