It's hard to go wrong either way, but I am in the Snowbasin camp. We just moved to the Ogden area (from Ohio) and one of the 1st orders of business was to get our season passes for Snowbasin. The price is quite high compared to midwest prices, but I feel it is well worth it. They have awesome terrain, limited crowds (especially on Sundays) and fairly nice facilities
Powder Mtn is also a great place to ski, but I feel that a pass is a better deal at Snowbasin. Powder is scheduled to open for the season tomorrow, where Snowbasin has already been open for several weeks. As previously mentioned, this is due to the snowmaking capabilities of Snowbasin vs. all natural for Powder.
Our plan it to ski Snowbasin as our primary resort and then head over to Powder after the big dumps.
