Sorry, Snow- disagree with you on several points here.
Yes, Utah is king when it comes to annual snow fall, so I will give them credit there. But their bragging rights are a bit exaggerated. It is known that several CO resorts do not include pre-skiseason snowfall (in otherwords, snow that melts early on) in their totals. Alta for example, includes all snow that melts in their total. Also, if you want to talk snow quality, tho not by much, Colorado has actually been proven to produce lighter snow. So we have the champagne powder.
Secondly, they say Colorado has 300+ sunny days a year for reason. Considering that we still do receive a decent amount of snow, how many states can brag that they receive many blue bird powder days like we do. Now, I've been skiing for 24 years, so that has provided me the opportunity to ski in other states including, New Mexico, Wyoming, Utah, Montana (as well as Europe) and I've often found their typical winter days to be overcast and sometimes even rainy. That sh!t gets old.
As far as terrain comparison? Are you kidding me? Colorado has plenty of sick sick stuff outside of the I70 resorts. Look no further than Silverton, Telluride, or Crusty Butt for example, and name one resort from Utah that offers more. And you mentioned crowds? Yes, I know the front resorts are bad on the weekends, but what makes you think Little and Big Cottonwood are any different? Those resorts are only a 20 minute drive from a major metro area and hell, one of the most crowded skiing days I've ever experienced was at Alta. The lines were so bad, everyone in my group went into the singles line to reduce wait time, and even that line was forming beyond the maze.
Lastly, skiing is a lifestyle (at least it is to me) and it's not all about the snow or terrain. Forget about Après ski? Ski town atmosphere? And let me tell you, outside of Park City (which also sucks), it is non existent in Utah. Anyone who doesn't believe in getting a beer at the base after a good day of turns should be damned to Fusker land for all eternity. Colorado reigns here.
