While I was in the city, the neighborhood streets were covered in snow and the tires still handled fine, no loss of traction. I honestly think the biggest factor in driving on snow/ice is the way you drive. That's not to say I don't think tires make a difference.
So I gotta comment. 6 feet of snow in 3 days. <pause for effect> But the roads were plowed and thus, you were likely driving on 1/2 inch of snow. On the counter side, without snow tires (caught sitting outside my kindergartener's school for pickup one day when a very sudden snowstorm hit), I literally could not get up my driveway. I doubt you would have made it with all seasons either. Winter tires give you a huge advantage in the snow.
My driveway....yes, that's a fairly steep hill right after the oak tree preventing any speed before the hill starts. Never had a problem with the LGT on snows.
