Keep in mind the Pro is only rated at 400 treadwear. The Pirelli does VERY awesome and has an 800 treadwear rating. All 3 seem to trade blows in the normal weather testing with the Pro edging the other two out, but at the price of only 400 treadwear vs 640 and 800 for the others. However, when the snow and ice test results are viewed, the CC2's slaughter the other two, which are fairly even. The CC2 stop on ice for example is shorter by over 3x the difference between the Pro and Pirelli.Heard good things as well, and they're on my short list for my next set, probably some time later this year. The other tire on my list is the Pirelli Scorpion AS Plus 3, tested here against the Michelin CrossClimate2.
