The biggest 3 problems for me with Apple Maps were that: 1) the map was zoomed in too far so I couldn't tell what turns were coming up; 2) as far as I could tell, there was no textual representation of how far I needed to go on the current road or which direction my next turn would be; 3) dragging the map is not a "thing" in Apple Maps. I like to be able to drag the map to look ahead at the route, and Apple just doesn't let you do that. You can only pivot around your current GPS position, and since you're already zoomed in too far, it doesn't help at all.
Apple may have "won" in the sense that they have claimed a lot of usage share, but from the perspective of a satisfied Google Maps user, I certainly feel like the end user has lost.
