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.

A few years ago I got annoyed at Google and switched to Apple Maps. Earlier this year I got annoyed with Apple Maps and tried Google Maps again before switching back. Point of interest data was a minor factor in all of this. It might be enough to lock me into using Google to find local businesses I didn’t know about before, but that doesn’t force me to use Google Maps for turn by turn navigation.
