Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
In my experience living in a very snowy area of the country, the key to snow driving is tires. If you have the right tires on the car, and I don't mean all-seasons, then you can deal with conditions just fine
now, with all things being equal...we'll say an identical model of car, either AWD or FWD, with identical tires, then AWD will be better
