I think it all depends on where you live and how much snow you get and how well they keep roads clear. We have three vehicles and all three have dedicated snows on them. There is no comparison between stock or even good all season tires to true snow tires on snow. I can easily out accelerate and brake shorter then a four wheel drive vehicle with all season tires, I do it all the time leaving lights in snow and they just stare at me funny. I have even had people ask me if it was all wheel drive, I just say, nope I just have good snow tires. I honestly can't tell you how many times it has saved us from a fender bender where someone else can't stop and slides through and intersection or just not getting stuck in a foot of new snow in a parking lot. Just yesterday I bet there were at least 10 cars stuck in the lot in Milwaukee and we just drove out, no slipping at all.
