Alta

I really, really like Alta. It has everything that's great about Snowbird (tons of snow, challenging terrain), while also throwing in some nice cruisers and more varied terrain in general for when you want to relax a little. Also, they don't allow snowboarders, which is either a positive or negative depending on who you ask.

I particularly enjoyed the area around the Supreme lift. Enough room to cruise, with lots of opportunities to cut corners, slip into the trees, etc to make things a little more interesting. I also really liked the runs off the Wildcat lift, though I wasn't quite a good enough skier to enjoy the stuff right under it.

I can't say enough about Alta. It really has something for everyone.
