I use two brands of snow tires only and they are Toyo Observe winter and Bridgestone Blizzak. They are awesome and you wouldn't be disappointed with either.
I use Goodyear Duratracs, although they are not a "snow tire" they do have quite a bit of siping and work phenomenal on snow and ice. I've driven a couple million miles and used numerous brands of tires, these tire impress me more than any other short of a studded snow tire which isn't overly practical for thousands of miles of highway use.
