I havent used the all seasons but the pilot super sport 4s tires are great here in southern california, year round, as long as you dont drive into the mountains to go skiing or something.
I run them year round here (and have used summer tires year round in southern california for more than 12 years). I dont ski or go anywhere where the temperature is under 40 degrees for extended periods of time.
The thing about the 4S tires is they also perform GREAT in the rain, which is what passes for "weather" here during the winter. My model 3 performance came with with them, and I have no intention of changing them for something else.
