Definitely pretty true. Lived in Tahoe for HS (So very familiar with Reno) and SLC last year, and SLC as a city is way sicker then Reno in my mind.
As for Tahoe vs Utah... thats a different story for me. Ill take the shredding in Tahoe over Utah any day. As for resorts I think the ski areas in Tahoe are better then Utah (quantity is part of this) and the backcountry is superior to Utah as well. This is just my opinion but its from a lot of personal experience.
PC does have a sicker park though then anything in Tahoe, Ill give Utah that.
People can argue the snow is better in Utah all they want, but at least in Tahoe it actually heals instead of having slides that are breaking several layers down in the snowpack in mid march. And to anyone that talks about "sierra cement," I feel like those people have never actually been in Tahoe during a storm. Or they rode Northstar for pow for some reason.
