Almost all alternatives use OpenStreetMaps. I prefer Magic Earth but all of them are similar enough
The main issue is OSM. They lack many addresses (varies A LOT among different countries, some are fine) and POIs. Please consider contributing yourself, because it depends only on volunteers!
It is SUPER easy. Just download StreetComplete on Android to add multiple different info in a very easy way (or just house numbers which are the most important info) and EveryDoor for POI editing/deletion/addition in just a few clicks. And don't worry if you don't input something because you aren't sure as long as what you enter is correct
