For a winter only tire I'm using the Blizzak DM-V2's in 17" sizing (down sized from the summer 20's).
For me personally, in my 33+ year driving career, I have experienced the most sure grip and safety with these tires. Yes, they are a few dollars more, and yes, they don't have a long wear tread life expectancy compared to other winter only tire brands.
But, the grip is and tracking in snow, slush, and all the winter crap in between is worth every penny (for me, anyways). I put my baby in 4WD and can step on it and there is not a lot of spin and side stepping. Just grip, launch, and GO... straight. The stopping is also excellent, too!
My truck is a 19' and I put my set on that winter, and got three full winters, plus a little the beginning of this winter, but they were done!
I just put on another set maybe 6 weeks ago, and good for another three full years (maybe a bit more..lol)
