Honestly, in my opinion, it's largely by volume. Frontier does have a lot of great themes-but it also has a lot of merely good or mediocre themes as well. It just has a much higher volume of music than the main series, and the good music sticks out more. I do still think frontier has on average better music than the main, but the primary reason it seems so much better is the volume.

Well, that, and us filthy non-frontier playing westerners haven't had to listen to those themes for hours on end, as opposed to the main series themes which we have.
