Replying to What utah season pass to get?

Ay everyone i got a job at a ski shop for the winter, first year out here moved from michigan. My options on passes are brighton, Alta, or snowbird. I rode all park in Michigan but am really looking to get into some good terrain focus on trees, chutes, maybe a little AT. So id really like to actually be able to ride park every once n a while but I have heard Alta snowbird don't have parks, but have crazy good terrain. I would be able to get the Alta snowbird combo pass for 350 or I could just get the brighton free. I guess what I'm asking is is Alta, snowbird terrain that much better to make up for no park? Idk what i should do any advice er whatever would be cool.
