I got winters on the GTA, and as has been said, it depends on your circumstances as to whether you need them or not.
I used them in snow last winter and as has also been said, it was like night and day. It went up hills of packed snow without even spinning the wheels, stunning grip
As for cost, it is slightly more to run them, BUT the17" winters on mine (Toyo snowproxes) are cheaper than the PZeros I use most of the year. Whilst the winters are on the summers are not being used. Apart from the initial outlay, its only the swapping over that costs, and if you time it right (ie when you need new tyres) even that cost is swallowed up.
Having used them now I would never go back to not using them.....
