While you are waiting for comment you may want to try a search. Snow performance has been discussed several times over the years.
How a vehicle does is somewhat subjective, what is important to you? The WK2 QTI is as good or better than any AWD type system out there.... but tires will make or break your day in deep snow. QTII and QD can be better starting from a dead stop as they have snow mode.
