I've been in a lot of bad snow (snow up past bumpers) in my lifetime, and I would think such a poor performance in the snow could hardly be blamed on any type of AWD system. My first car that was AWD for the snow (Audi A8) was the last car I bought for the snow. Drove strictly RWD with powerful engines and zero traction control the rest of the time.
Even given those "awful" circumstances, I never found myself in dire straits with good snow tires. Only trouble I ever got myself in was if I happened to come to a dead stop on solid ice formed from running water (tends to be a lot slicker than ice from standing water). Then, I was going to be doing some goofy stuff to get out, but never had trouble otherwise. I was pretty notorious for ramming my cars through snowbanks to park in the unpaved sections of the street, and then driving straight out without any drama.
Whatever my Audi had going on for AWD, it simply supernatural in the snow. I had figured a heavy car with AWD would be, and it did not disappoint.
