I've been using Apple Maps as my regular navigator since iOS 15.0 general release, and I've been impressed.
The audio directions are much clearer - e.g. "Go through this light, and at the next one turn right".
The integration with Siri and CarPlay is very handy - e.g. "Hey Siri, get directions to Bob's house".
And the traffic data is noticeably better in the last year.
Disclaimer: I live in suburban U.S. - I've heard less good things about AM in rural areas.
