I use Apple Maps pretty much every day and definitely every day Monday to Friday for a 35 mile each way commute to work. Tried both Google Maps and Waze at times but always go back to Apple Maps. Prefer the look of it, hasnt let me down in terms of routing etc and traffic etc is pretty accurate plus it integrates into the calendar for picking up destinations and how my phone learns where i go a lot etc to suggest routes. A lot of the time i dont even have to mess about choosing where i'm going as when i start Maps on CarPlay it suggests the correct destination. Used it in the UK, France and the US with no issues. The only time i didnt use it in the US was because we were up in the Hope Valley in California with no phone reception so i'd used the Offline Maps function in Google Maps to download a big chunk of map as i knew the hire car had CarPlay to use for navigation.
I really dont like the look of Google Maps and the usability of it via CarPlay and never really got on with Waze for routing etc. The user entered stuff on Waze is handy so sometimes i will start it so its running in the background and you get alerts from it over the top of Apple Maps as well. I have all three enabled on my CarPlay screen just in case but 99% of the time i'll use Apple Maps.
