I made it up to Mont sainte Anne last February. Big mountain. I would say the bump runs down the front are comparable in steepness, with and length to Sugarbush and Stowe. Neither of them really has those broad , steep, sweeping groomers Sainte Anne has. However, I think each of them has some slightly harder expert terrain. Jay Peak is a completely different mountain. The trails are mostly so so. You go for the snow and the glades and tree skiing. If Sainte Anne was lacking anything it was glade skiing. There was some. just not a lot, not as extensive and not with that in the thick of the woods feeling you can get at Jay.
Sainte Anne, is a big, beautiful mountain with something for everyone. There were no crowds, at all, last President's week. They were not even charging holiday rates, though I understand that may be changing.
Oh, and they have an excellent lift system too.
Sadly, I didn't make it to Le Massif. I know what you are going to say, "It's bigger and steeper." I say, "Good reason to get back up there!"
Can you get a tax refund when you come back into the states?
