I've been happy with my Discoverer AT3s. Quiet on the road and good for trips to the snow on Mt Hood on the weekends. Never run the Duratracs, so I can't compare, but I've been pleased with the AT3s. I do have the 4S compound, which is supposed to be better for snow and ice, so that's something to take into account, I know there are a few versions of that tire.
