The top of Powder Mountain is the same elevation as the base area at Alta. In addition, their annual snowfall is a lot less than the Cottonwood Canyon resorts. PM is a fun mountain, but not a good early season choice, unless they are having an unsual snow year.
I myself want to try Snowbasin / Powder Mountain to avoid the crowds, but considering the timing of your trip (early winter essentially). And the location of Pow Mow / Snowbasin. You will need to consider the weather first of all.
Snowbasin and Powder Mountain are lower in altitude. So the snow might not be as abundant. I've never been to Snowbasin, but if I recall due to the direction the mountain faces, the weather can be pretty iffy.
