For All Weather, not just for winter. It is better than stock Tyre in any condition like dry, wet etc.
I've been using Crossclimate+ on M3 for 3 yrs, it's a great performance in all weather, especially on wet rainy roads, it saved me to avoid the forward collision. (saved my time, several months for waiting to fix, also money or hassle with insurance)
Below is just numbers, but you can feel much better in actual life, near miss, etc.
And this is just my own opinion, only Michelin has a Similar Performance when the Tyre is nearly worn out.
