How do Nokian tires handle in snowy conditions?

I'm curious to hear about how Nokian tires perform in snowy conditions. As an owner of a few Nokian-equipped vehicles, I've had mixed results with their performance on snow and ice. Some models seem to handle well, while others leave something to be desired. I'd love to hear from fellow forum members who have experience driving in snowy conditions with Nokian tires. What brands and models do you prefer for winter driving? Have you had any particularly harsh or pleasant experiences with your Nokians? Some specific questions I'd like to ask are: * Do the Hakkapeliitta and Rotiiva lines hold up well on deeper snow? * How about the Hakkapeliitta studded tires - do they really make a difference in icy conditions? * Are there any particular features or technologies that help Nokian tires grip better in snow and ice? Any insights or experiences shared here would be super helpful!
