Same here, been using it for a few years in the Bay Area. The main reason I prefer Apple Maps is that the user interface is vastly better, especially in a car with CarPlay. I’ve used it on long road trips in the US as well, but I will often do a route sanity check against Google Maps in areas I’m very unfamiliar with.
I only drive in rather large cities, and find that Waze >> Apple >> Google from a usability perspective; Waze and Google Maps supposedly
Use the same backend these days, but somehow both UI and navigation in Waze seems to work better.
I really really like OSM through Organic Maps (previously through maps.me) but it has no congestion data, so mostly useless for driving during business hours.
I find it to be better, but there’s a major caveat that I primarily use it in the Bay Area.
Outside the bay it’s worked for me too, but it’s just rare that I test it in that way (where failures are a lot more likely).
UI is much nicer and app performance feels way faster too.
