I live north from Michigan, so a bit more snow and colder. For most of my life it was All-Seasons. Always thought winter tires were best, but never did it. I finally made the switch to real winter tires on a separate set of wheels when I bought a used 2014 Mazda 3 that came with the extra set. I realized the first winter they DO make a noticeable difference. A couple years later my son and daughter both bought new cars and also bought wheels and Hakkapeliita tires for winters. They agree that works better than the previous cars they had with All-Seasons.
Two factors. One certainly is cost up front. For the TIRES, you just spread mileage over two sets of rubber, so the per-mile cost is nearly the same. But you DO spend maybe $400 for the extra wheels to last the life of the car. I think that's worth it if you can come up with the initial money.
But here's an important cost item: switching over. If you do this your self for free, no real cost - just some time, and you get total control of tire rotations, etc. BUT if you take to a shop twice a year for swapping wheels, that's a bunch more money - where I am, typically $125 for a 4-wheel swap, twice a year.
