I would still suggest, anecdotally, that Google Maps is a bit more up to date and comprehensive over Apple Maps. However, that has narrowed a LOT over the last few years, to the point where I really don't worry about it much. I prefer Apple Maps' interface, smoothness, etc. over Google Maps. GMaps is still a good app and a great mapping/directions tool but being in the Apple ecosystem, Apple Maps works about as well (or close enough that it doesn't matter much, at least to me).
