Mammoth is the best of the big American ski resorts. It almost always has the most snow and it doesn't rain there like Tahoe and has the most lifts and skiable acres and some of the hairiest runs. I've been to Steamboat, Jackson Hole, Kikwood, Heavenly, Alpine Meadows, Mt Bachelor, Alta, Snowbird, Brian Head, Snow Basin, Mt Ashland, Mt Baldy, Snow Summit, Snow Valley, Mt High, Snowbowl, Purgatory, Arapahoe Basin. June Mtn is my second favorite and Brian Head and Snow Bowl and Steamboat then Alta and Bachelor.
