I like Apple Maps over Google Maps for many reasons, but the primary is potentially also the silliest: while driving, the "you" icon is smaller and its location timing is different than Google, making turn-by-turn directions far easier to understand in an area I've never seen before. When I'm trying to see if it's the next street or the street afterward that I'm going to have to reach, the little bit of timing differ…
That's interesting. Last I tried Apple Maps a year or two ago, it was the reverse. The indicator in Apple maps tended to "lag" a bit, especially in roundabouts (I'm in Europe). With GMaps, it would always be quite clear where exactly I was with respect to exits.
Also, on a turn, the Apple Maps indicator would turn on the map, so again, in a sharp turn, or a roundabout, I wouldn't see much of the road ahead. GMaps would turn the map and keep me facing north, so I could see what to expect further ahead.
