Better listen to the disclaimer and ignore everything elseDisclaimer: I have not driven in snow on any of the tires mentioned above.
Something tells me that a lot of things depend on the snow (deep, moist, hardened, etc) and the kind of driving you plan to do. If you are talking about somewhat well packed deep snow, you probably want to float on it, not dig in. For floating you would want to get the widest footprint and moderate "claws" in order to prevent digging yourself in. If that is the case, then you should probably get all terrain tires and deflate them.
Now, if we are talking about not soo deep slushy snow, then you probably want skinnies at normal pressure so they can dig in through the snow, hit the ground and let you use the traction that comes from the tire-to-ground contact. Then I'd vote for an MT tire that is known for NOT packing snow.
I have heard that Firestone Destination M/T is somewhat in the middle between AT and MT. Also, take look at Cooper ST which is a bit more aggressive then BFG AT.
I've been incredibly happy with my AT2's over the past couple months, and we have had a boatload of snow, and resulting ice conditions. I wouldn't hesitate to buy them again.Now that being said, this time around when i need new tires i will try out the General grabber AT2.
