if you like drugs, summit county/Breck
if you like a park that's not super crowded, Keystone or Park City
If you hate crowded parks but have to live somewhere with nightlife, Park City
if you want more options/really sick powder days=Park City (Park City powder is pretty much on par with summit county resorts, but if you go to big or little cottonwood canyon you'll find the best terrain and snow.
lift tickets to SLC area resorts are generally in the $50s-$60s if bought at discount at like REI, compared to $100+ in Colorado
