Tough question for even an expert to tell you. You never know when lake effect snow can dump the Wasatch Mountains... This isn't a La Nina year, or else I would say head to the PNW over all these.
Weather is a lot of luck & patterns for either state, but the climate for SnowBird/Park City generally gets many lake effect or lake enhanced storms.
In SnowBird, we had over a foot in early April '12 come in a early morning squall that came from no where... it was all lake effect. SnowBird got 12" Park City recieved rain & couple sloppy inches, I'll never forget what 9 or 10 miles can do. So, in general, I think Wasatch has better chances than rockies for lake effect, but given years who knows where more storm patterns hit - if it's Utah or Colorado.
I can just tell you - the Wasatch Mountains are ripe for lake effect with a nice cold NW front.
