park city for park, NOTHING else, expensive tickets and a shit load of rich annoying people
Brighton for fun terrain, not quite as many people, tons of boarders, decent parks and good pow.
Solitude for very good pow, hardly any lines, cheaper tickets, and very very good terrain up top (honeycomb canyon is one of my favorite rides in utah)
Alta for skier only, good terrain, not a ton of people, decent ticket prices, decent pow.
Snowbird, meh, im not personally a fan of the bird, tickets are expensive, there are a lot of people, terrain is good, but not better than brighton, solitude or alta. i just dont see a reason to go here unless you want to stay in a hotel with a sweet pool right at the lift line.
personally my favorite is solitude, its quiet, has good terrain and pow. doesnt have much for a park though if your looking for that. for park, just go to brighton, good pow, good terrain, etc.
