Apple Maps has been good for a while now (3 years?) at least on core functionality (navigation, street names). I would say in terms of navigation, Apple Maps is superior to Google Maps. Apple Maps is more accurate about which lane to be in, shows the stoplights to pass before crucial turns, and labels the streets to skip over before turning near your destination.
They don't have the same content features of Google Maps yet. You may have noticed Apple integrates with Yelp to provide you with feedback on restaurants and points of interest, but in my opinion Yelp is unreliable. Also since Google cares less about marketing a pro-privacy stance, Google shows you how busy locations are, which can be useful.
On a more neutral note, it would be nice if either Map app re-routed common commute routes based on traffic incidents. Anyone who commutes down a contraflow lane knows that an accident in that lane makes it worse than the main route.
