Hey! I actually live in Vail and work in Beaver Creek. Congrats on getting a job in Breck! I think you'll really like the snow out here. The powder days are fantastic, but it's true that it gets tracked out fast. Although, the local's know where to go to keep getting fresh powder, which you'll definitely learn.
I like Breck, but it is pretty flat (a lot of people complain that it's a 'beginner's mountain'). It does have a great park, but Keystone and Vail's park's were better. Vail's great, but it is huge. Personally, I love Beaver Creek and spent most of my days there last season
