Michelin X-Ice is consistently ranked in the top 3 of studless snow tires. And is the best I can find available in the US market, see link below.
If ice is a major problem, then studded is the only way.
Braking on ice (31mph - 0mph)
Michelin studded = 53.9m
Michelin studless = 61.0m
Acceleration on ice (3mph to 12mph)
Michelin studded = 4.7 seconds
Michelin studless = 5.7 seconds
If virgin and plowed snow, packed snow, rain and slush is the problem, then the good modern snow tires are very close to being as good as studded.
Braking on snow (50mph - 0mph)
Michelin studded = 52.6m
Michelin studless = 54.3m
Acceleration on snow (3mph to 22mph)
Michelin studded = 5.6 seconds
Michelin studless = 5.6 seconds

I pay enough money to the car insurance company that I don't need some accident jacking it up, then left wondering if a good snow tire would have prevented the problem. Besides, once the snow tire is bought and used only in winter, it increases the life of the 3-season tire (especially since I'm not spinning the tires on the pavement as much) and so I figure that the total money spent equals out in the end. So by my reckoning, reduced chance of accidents for almost no extra money.
