I live in Denmark, and here is Here best -for me!
It seems like Here is more detailed - 2 examples:
1: Close to my home there is a small path between 2 minor roads - it is on Here and not on TomTom.
2: The office where I work in is in a "back-alley" in the outskirts of Copenhagen - the "road" is in Here and not on TomTom
