K-Dot.Depends on what you want.
PC/Canyons - Best parks
Brighton - Mix of park with terrain
Solitude - Low key with terrain
Alta/Snowbird - Best terrain and best snow
I took a trip out last February(yes, when the snow sucked), but we went to almost all of the resorts in the area and I'd agree with everything this guy has here. Plus I'd add Canyons/Park City has some good areas if you're ready to hike a little. Also Deer Valley is a great option if you are going with you family. The on-mountain facilities are A++ as is the food.
