A lot depends on skills/experience.
But I've both AWD and none AWD with snow tires in different conditions and hands down AWD+snow tires =awesome.
My old car was a WRX with 17in blizzak LM25s and I drive during the middle of the blizzard of 06 PASSING all the highway plows
my current car a 335XI has Dunlop Winter Sport 3Ds and they do well, not as well as blizzaks in snow but when its dry to rainy they are better.
