I love my Michelin PA2s, but don't know how they compare with other tires. I drove on them every day in two Minnesota winters (very cold, not so much snow). If you spend much time traveling distances on the highway, I think the PA2s are quiet and ride well and wear like iron. They were good up to the point my car high sided in the snow.
It's warmer here in NY with significant quantities of snow. I'll drive on my partially worn PA2s for the first part of winter and then decide if I want to buy a different brand (because the PA2s will be worn out) for the rest of the winter.
