I've been to both multiple times, and I prefer Jay by far... Best glades in the east, better snow, laid back vibe, less french Canadians (sorry Quebecois but you don't rub the rest of Canada the right way!).
The ski and stay deals are pretty good, but especially since you're booking early I'd call them and try to bargain.
