I'm really surprised at the low rate responses like getting stuck in 4 inch of snow or up a hill? Something other than the tires is not right like the driver or the tires were not downsized or rotated.
I suspect so since, I drive a lowered sport RWD car for goodness sake and I have none of those issues that these people speak of.
I've had these tires now for 4 years and they performance just like they were new in SNOW, SNOW covered ICE, ICE, black ICE.
I live in Toronto and drive daily, up, down, and around.
Went into an uncleared parking lot with at least 10 inches of snow a couple years ago. Never got stuck once. Stopped and started with ease just for fun!
By far "best overall" among the ones I've had throughout the years: Winter Viking, Yokohama iceguard ig20 & ig52c, Gislaved Nordforst 5.
I've tried the new Yokohama IG51v on my '15 Sorento SUV and they did not perform as well as the Xi3 on my rear wheel drive car in the same parking lot. The SUV actually got stuck multiple times. I also have NordFrost 5 on my '02 Corolla, older Yokohama snow on my '96 Integra, and Nexen on my '97 Maxima. General Altimax on my '12 Rogue (RIP). The Xi3 have been the best so far in ALL conditions. Dry handling was very surprising to me as you can see I have several other tires. I had better traction going uphill than my SUV on the same hills too. I used to drive 30,000 km a year 6+ years so I have tons of experience on snow tires alone.
