I think a lot of this can be explained by Killington's market drawing from Montreal, most of New England, New York, and the Mid-Atlantic. They want to make sure they are ready for the crowds. They focus on base depths and trail counts up high so that when they are top to bottom they can move around the crowds.
You are much more likely to see Sunday River go top-to-bottom first. Their goal is always early season terrain expansion for the weekends. They don't mind closing mid-week as they draw from a more limited market. They split the Boston and Montreal markets with Killington, but get very few people from the Mid-Atlantic, New York, and Connecticut.
If you're location dictates that you're stuck skiing Vermont for practical distance reasons, keep an eye on Okemo. They won't be open for another couple of weeks, but when they do they'll be less crowded, better groomed, and more accessible.
