You forgot tires in that stopping equation. Do you live someplace with a lot of snow and ice? Get really good winter tires. Only get studded tires if your winters are constant snow and ice in the ground, and there are some very good studless winter tires: blizzak, X-ice, hakkapeliita etc. Good winter tires will decrease your stopping distance compared to all season.

You’re right. I just realized a minute ago that I forgot to mention tires. Whoops! Well, the point is still valid, so I’ll leave it.
