The grass is always greener on the other side of the fence, but, the snow is always deeper in the Rockies. Also, elevation can be relative to emotional experience via thinner air where sounds travel differently and people get adrenaline quicker sometimes. There is also the vertigo feelings that make skiing a rush. The bigger mountain you stand on, the more intense those things feel.
The advantages/disadvantages of Midwest skiing is proximity of ski hills to large metroplexes and long seasons due early frosts and snowmaking. Let's throw in night skiing too.
Now Skiing in the Southeast is a combination of some of the advantages above. The elevations are higher than those of the North East and Midwest, but nothing above about 5,500 elevation. We have night skiing at most places.. But, we don't get the major dumpage that the Rockies.
The Mid Atlantic gets a bit more natural snow and has all the infrastruture (snowmaking, modern lifts, etc) that the South east and Midwest have. The average elevations are a bit less than the Southeast and a lot more than the Midwest.
The upper East has longer seasons and more skia area options to choose from in any given area on any goven day.
So for the USA I'd rank the regions as follows:
1) Rockies, including Utah and PNW
t2) Upper East
t2) Southeast (NC, TN)
3) Mid Atlantic (PA,, WV, CT, VA)
I know what you're thinking... "How can anything side of the equator that says "South" be good skiing"? Shhhhhh... Keep itunder your hat please
Also exatly what is Southeast versus Mid Atlantic is alwasy debatable. Some include VA and WV with Southeast and some include Georgia and Alabama with Southeast.
One could also flip Upper East and Southeast because many uper East resorts have more than the 1100 vertical that the better Southeast areas offer. I can agree with that. More snow and more vertical might trump summit elevation.
