I can't even get up my (paved) driveway with a FWD car, a few times every winter, nor out of my neighborhood up a steep hill until it's been plowed and salted. Never had a problem doing these things with a 4WD/AWD.
I bet you would like some actual Winter tires for your driveway, in that snow and hills. My AWD Mercury with the Blizzak's would barely break the tires loose on a slick snow packed road. With any all season tires, or any non Winter tires, I could spin tires easily on packed snow.
The actual Winter tires have a ton more grip than non Winter tires. I went up a hill in about 2007 that was steep and a day old snow. I just walked right up it, turned 80% from the top(backed down right to a mailbox(NDCBU)), then turned right and went to the top, spinning the front tire(stock open front diff). Going down was the scary part, I knew that was the dangerous task. The people who live there park at the bottom of the hill, about ten vehicles. There were half a dozen people watching me go up, figuring it would be typical fun to watch another car spin and slide down. I walked that Mountaineer down that hill with no sliding, and while doing it, I knew it was a mistake to go up there, and I wouldn't risk it again.
That was West Casey Drive in 37862 if you want to look for that on the Google earth that shows pictures of street level. It's a steep hill, not that long but if you slide, there's a deep ditch at the bottom. The Blizzak tires were the trick to get up, and down that hill. The AWD did nothing to save my ### coming down, the Torsen rear diff, that was more help than the one front tire pulling. If I had used all season or low level Winter tires, I might have gotten up that hill, but I would have wrecked coming down it.
People forget how differentials work, a 4WD with two open diffs, is just a one front and one rear drive vehicle. Having an open front means you have three wheels pulling at most(with an LS rear).
