I think in years gone by I would have sad AWD for sure, but I've since changed my mind. In winter, I would go RWD + winter tires every time (regardless of snow btw).
If you need AWD because you rely on your car to get you through here snow (and assuming snow is a fact of life where you live), then you should probably have a 4x4 for that.
This has been debated before btw:
