With good winter tires, any of the normal routes should be fine. More major highways tend to get more frequent snowplow visits. I-15 to US-89 to I-17 seems to be the most expedient route.
With all-season tires, you will have to check on the expected snowfalls and the elevation of the passes through which you may drive. Some of the higher elevations may require you to carry snow chains, and if so, you should know how to use them.
