I think one thing that is missing from Apple Maps is approximations. Google does the "Did you mean" thing when it doesnt know. Apple Maps just says no results.
I just looked at Nokia's Maps, and they use address approximation as well.
Bottom line:
Both the free Apple and Google navigation apps provide clear routing directions. Apple feels like a less-mature product. But as seen with the initial competing applications for the iPhone, we would expect updates to this new app over time--and Apple has promised as much. When getting down to the nitty gritty, Google provides a better overall package, but we feel that both provide a good solution for standard software. We expect the competition between the companies will benefit customers with ongoing improvements.
I'm liking the Apple Maps a lot better.
Yesterday, my wife and I were looking for a store and couldn't find it. She was on a 4S. Google was just dropping the pin at the street where the shopping center started. Pulled out my phone and looked for it, and it dropped the pin on the store itself, letting us find it in a corner of the shopping center we just couldn't see until we pulled around to it.
Not that my experience is the end all be all, but honestly, I've had nothing but great experience from the Apple Maps app. It even knows where the pizza place is down the street from my house, something google hasn't fixed in about two years, no matter how many times I've reported it.
As reported by Amit Agarwal, at his Digital Inspiration blog, Apple has since updated its description of its Maps app to omit any mention of Maps being amazing, awesome, or any hint that it's the top dog on the mapping market right now. In fact, the entire sentence praising Maps has been replaced with a new sentence that has nothing to do with the app's quality, but rather, its interface.
To the casual observer it might appear that Apple was caught off guard by just how bad its in-house maps app was. But the company had plenty of warning.
Developers have been complaining about Apple's Maps since shortly after they were given the first pre-release version in early June, CNET has learned. They say they filed bug requests, sent e-mails to specific Apple employees, and vented on message boards only other developers and Apple could see.
Apple had been warned about its map's quality.

I don't think there's any way that they couldn't have known. They chose to release it anyway. Either they were fine with it shipping in what amounts to beta status or there's a disconnect between their mapping team and the executives at the company.
