Hills are different everywhere. The hills in Colorado are long, but rarely over 7% grade. In the North Georgia mountains, we get 9-10% grades, even sustained 13%. I had no problem climbing the Rockies on a double with a big (13-29) cassette, but for Georgia, prefer a compact. With a 13-29, I get the same gearing as a triple.
