Frankly both Apple Maps and Google Maps could stand some UI improvements. Google Maps won't shut up, throws up some bizarre progress bar even on mute, has mystery meat navigation, and replaces the map with some giant material design-style empty space when it decides I've "arrived" (even if I haven't).
Apple Maps used to make it hard to pan around, but that's been fixed in iOS 10. Instead now it has terrible bugs in landscape mode, and has adopted the "you've arrived, now you don't need the map any more!" behavior.
If they just let the map be a map...But anyways I'm old enough to remember pulling over to pull out the giant paper map in San Francisco, so I can't get too upset. Either one has made my life so much better.
