Which company makes the best snow tires (goodyear, etc...)?

I have a 2002 Ford Explorer Sport and I need to buy 2 good sets of snow tires for my SUV. Snow is horrible right now in Erie and my car fishtails sometime, not to mention I have gotten stuck twice in my apartment parking lot (huge build-up of snow)! Please advise! Also, would snow tires increase the resale of the vehicle? Thanks.
