The current weather and conditions are meaningless for March.
This is mostly true. As bad as the 2011-12 and 2013-14 seasons were, March was the one month skiing at Tahoe was fairly decent.
Early March is the start of the timeframe where altitude and exposure become important for ski conditions. Anything you plan far in advance will only have a ~15% chance of fresh snow on any given day, so you should be at least as concerned with surface conditions on the other 85% as whether there is new snow.
But basically you have chosen the overall most reliable timeframe for snow conditions at the vast majority of destination resorts. So your decision should be based more upon your other preferences.
More specifics to your questions would be helpful. What level skier are you and what kind of terrain are you looking for?
Does atmosphere mean a compact walk-around resort town vs. a multi-resort destination like Tahoe or much of Utah where you drive to multiple areas in the same region? Colorado has so many resorts we really don't have enough info from you yet to narrow it down.
Mountain scenery is subjective. In general I'm more impressed with it in the Pacific States than in Utah and Colorado. Telluride is the obvious exception to that sweeping generalization.
