Edit: The commentary that the reviewer makes in the video about the real winter (nordic) tire vs. the regular winter tire is backed up by my experience as well. Nothing touches a true winter tire on icy surfaces. "Performance" winter tires feel like all seasons, just a little bit better in icy conditions.
