Apple Maps is also the only app that shows the exact entrance and exit to take on public transport in the cities I’ve used it in (Vienna, London: esp. time-saving there with often exits numbered 1–5 without clear indication where they lead to), and the station layout with underground walkways overlayed on the map is also very accurate.

The only annoying UX gripe I have is that it doesn’t show the arrival time, you have to do your own mental math to add the route duration to the start time you’ve entered.
