VERY good question! I'd like to know myself.

A couple years ago, CR tested winter tires -- both H-rated and Q-rated. Unfortunately, they were rated using a different 'scale', so you can't compare them directly ("good" dry handling for Q-rated tire might be "fair" or even "poor" for the H-rated group).
