I don't really understand the logic, but there are plenty of reasons to not be using Google Maps, so I will give my two cents.
I have had the best luck with MagicEarth. I still use Google Maps sometimes when I need to use the most reliable navigation or if MagicEarth can't find something. When I was driving professionally I found out that sometimes MagicEarth (OSM) got residential addresses right when Google Maps did not but also vice versa. I have used HERE Maps (HereWeGo) in the past and also tried OSMAnd.
