I've driven the 911 and 924/944/951 types as daily drivers in some pretty big snows.
I always preferred the 911. Sometimes steering would be too light, and in deep snow could pancake underneath, but usually good traction. For the 944 type cars, even with the extra transmission weight in the back, they didn't seem to hook up as well as the 911, or as well as I would have expected even with the 50/50 distribution. This is with all sorts of tire combos, but I'm not as far north as CP, no ice driving like that
That's just my opinion, other's might have had better luck.
