After skiing these places almost exclusively for decades you have no opinion who gets more snow???
I have been involved in evaluating "brochure quotes" for areas where I do not collect formal data. The people who know whether brochure quotes are realistic are locals who ski these places regularly. Thus my persistence in this thread.
From what I see here, you NY region locals seem OK with both Hunter's 71 and Belleayre's 140. There is logic that Catskill snowfall would decline NW to SE but by 50% is a lot.
