sabaton has a strong habit of overplaying their music. they play complicated tones and combinations so fast that they often get lost in the drums and guitar riffs, so here, you can hear all the individual elements of the song more clearly, making it sound more complicated than the original, and also, these versions play much better on very bass-heavy speakers and headsets, which at the moment is most speakers and headsets. nightcore on the other hand is for people with a fetish for squeaky noises.
