Difference is pretty big if it’s icy like breaking 100 meters vs 10 meters. Especially if there’s wildlife like reindeers/moose’s you are going to do emergency breathing semi regularly.

If it's icy there's no difference at all. The only tyres that do anything on ice are the ones with spikes or chains.

If it's snowy a good modern all weather tyre can hold its own, but will brake a few feet later than a good winter tyre.

In all other conditions a good all weather is a lot better than winter tyres, and pretty close to a good summer tyre.

You must live in Florida or be a terrible driver. The difference between winter and all seasons is very apparent.

I... Well, I had started explaining point by point how wrong this is but frankly the answer is just "all of it, very".

I've driven summer tires, all season tires, winter tires, and studded winter tires in every season in Canada. (Yes, I live in Canada and own borderline-usless summer-only tires. Yes, I've tried driving them in snow.)

None of what you're saying lines up with my own experience, various YouTube videos on braking distances, or literally anything else I've ever seen anywhere.

Edit: And, well, to be clear... I've lived on the West coast of Canada where it's a bit more mild but you're in the mountains, in the middle where it hits -50, and in the East where it only hits -30 but snows like hell.
