Even Apple Maps is heavily, heavily behind Google Maps simply because very few users are entering Point of Interest info into Apple Maps.
New restaurant opens, or store closes, or opening hours change? Google Maps has the updated info within a few days. Apple Maps in a year or two, maybe.
That's the moat. The only way either Apple or the other corpos catch up is by offering massive financial incentives for their users to contribute PoI data.
It may not matter for your purposes (i.e. replacing Google-Maps-the-product in your daily use as a consumer).
I'd naively expect that having hundreds of thousands of Amazon drivers dogfooding these maps daily does help with data quality though. So maybe OSM dataset works best as a Google Maps replacement if you can shoehorn your usage into something that overlaps with the things a gigantic logistics operation cares about.
