Replying to Questions about Aspen

So my girlfriend and I are moving to Carbondale, CO in August because I'm going to school. Im gonna be skiing Aspen and am curious where I'm gonna find the best terrain out of the 4 resorts in the area. I live in WA right now and have been skiing Baker, so i'm way more fond of powder and skiing lines than I am at skiing park.

So where am I gonna find the best terrain? Cliffs and pillows, steeps etc. Highlands, Buttermilk, Snowmass, or Aspen Mountain?
