Everything from the UX to the clarity indicating street names is far superior on Apple Maps.
One thing I always hater about Google Maps is that it doesn’t show you street names when you need them. I was in NYC a while back and I wanted to see the street name and I had to do lot of scrolling to find it.
I also wish Apple has better metadata about businesses, sometimes it shows a restaurant as closed when it’s actually open or vice versa.
Overall I am glad i switched to Apple Maps
