Lemme throw some knowledge at all the readers:

This all depend upon where one lives and how many snow days (as just one evaluation) one gets.
Living in Michigan, for instance, I find that there is a big difference between snow accumulation in the northern parts of the state and the southern parts of the state and, as a result, different tire preferences.
