My ten cents:
Jay:Always had good luck with snow here, magically snows alot more than everywhere else, although it gets windy as fuck which shuts down the lifts more often than other places. usually not a huge issue if you're there for a few days. Trees are the shit, and i've never skied anything like the ridge o the east coast. can be pretty gnarly. Parks have been alright in my opinion, good thing is that they're at the bottom of the mtn so you can hit them after hitting some of the good stuff up top.
Bush: haven't been in a year or two, but little bit of everything there. Castlerock area is pretty sick and also alot of good trees everywhere. Park is self explanatory if you've ever been on NS you know it's good.
Never been to sugarloaf.
Went to whiteface when i was 8. It was Icy. I didn't enjoy it. Sure its alot better any other day though.
Enjoy your trip hombre.
