I've had the P Ice and Snow in the past in 19's and they're great! Another member bought the set and was really happy with them as well... I'd recommend getting them if there's difference isn't too big...
From my snow driving needs I never really needed to push the tires close to its limits or even up to 75% so your choice should also really depend on your needs and type of snow/ice covered roads you drive on.
Tirerack reviews should help once you understand your snow driving needs as you'll be directed to the better performing or mid performing tire.
G/L!
