I am a skier.  The ski areas that I have been to are Deer Valley, Alta, Park City, and Solitude (all in Utah).  My favorites are Deer Valley and Alta.  I am unable to choose only one, as each resort has something very different to offer.  Deer Valley provides a level of service that is unlike any other ski area; hence, the reason why they were rated the #1 ski resort in North America by the readers of  Ski magazine.  (Not to mention their food is really, really good!)  Alta has the best terrain that I have ever skied.  As far as my ability goes, I will go down anything.
