Replying to Is Breck only good for park?

So i am going to either breck, vail, or aspen/snowmass for the first week of march with my family. Obviously, i know breck has a sick park but how is its terrain besides that? I would be skiing for 5 days and 3 of those days would be with my dad who loves steep terrain and good scenery, Is the top of breck entertaining enough for 3 days without getting old and do they have enough variety? Vail is appealing because it is huge and has blue sky basin plus a decent park. But i was really curious of how great the bowl skiing is a brick and the steep tree skiing?
