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.
On iOS? You can tell Google your home/work addresses in settings, I ask for directions/transit home multiple times most weeks and it works. On Android they can figure them out, but on iOS they don't have enough permissions and you'll have to tell them - but when you do this works.
Instead they want me to sign into Google and it wants that info to then be stored on Google's servers.
All of them are far from perfect, but vastly better than what we had before.
At any rate, sure, Apple Maps isn't as good yet. They launched years after Google Maps and with a much smaller team. (There are some interesting politics behind that, from what I've heard; just say that the fiasco of the Maps launch is the primary reason Scott Forstall is no longer with the company.) The team now numbers over 1000, from what I've heard, and I expect the gap to continue to close -- but it's going to continue to take a while.
I have given up on using the default map for searching anything. Of course the map content itself is the same, but what good is a mobile map if you search for a coffee shop around you in New York and it gives you some grocery store in Scandinavia? I would be forgiving if this happened rarely, but to me it happened very often. I have 4 iDevices and they all have the same problem. This never happens with Google maps.
