It’s pretty impressive in my use across the US. Listings are not as good as Google Maps, but the directions are as good yet it looks much nicer.

However I spent a lot of time in West/South Asia. It’s functional here, but Google Maps takes a big leap here since user suggestions and corrections are implemented much quicker.
The Apple Maps team is very slow to react, which is unfortunate as many roads are places are way off.

LADDA are my go-to as well. I recommended going with the wall charges and not the USB-A charger, since the latter juices them up very slowly (compared to the wall outlet or the storage+charge box).
