It still has a pretty useless database of locations. The listings for many shops/venues in my area are literally years (sometimes decades) out of date, even after I reported them back when iOS 6 was a beta. This is slowly improving, seemingly starting with locations that are commonly visited, but it's still not there. However, given that most of my use cases are "Enter post (ZIP) code, go there", this doesn't really matter. 90% of the time, Apple maps works fine, and there's no reason to use something else, especially when it's ad-laden.
Given that maps are not a core concern for Apple, I've always been surprised they've not just thrown money at improving open street maps. A few hundred million to setup an "OSM foundation" (or fund an existing one) could seriously help them (decent free mapping database to use), and hurt Google (major commercial advantage limited/eliminated). They could probably get MS onboard as well.
