Suspension Breakdown

So I’m planning to get some parts for my car during the winter. Seems everyone is doing this now eh? Well the first thing I plan on getting done is the suspension, which would seem simple enough but i’ve hit one snag: what strut to use…

The choices are Tokico Blues or the KYB GR-2. Basically which one is better for performance driving. And has anyone heard if these cannot be used in the winter?
