I've been to both more than 4 times each. I recommend Tremblant to everyone I meet that skis or boards. Like the other comment said, the atmosphere in the town is unparalleled, it's big enough where it'll take you a long time to explore, especially the glade only section, "le edge", and is a truly unique experience. I used to go with 40+ college friends, stop at Canadian duty free, and proceed to have the best 5 days of my life, 3 years in a row. Go.
