Detroit has some great suburbs (check out areas like Ferndale and Plymouth/Canton), but don’t write off Detroit based on what you’ve read in the media. A lot of people in Michigan are in the same boat as you and are missing out on what Detroit has to offer because of what they think Detroit is.
I was on vacation recently and Apple Maps gave a weirdly circuitous route from our hotel to a restaurant. I checked Google Maps and it showed the direct route I expected, so I went with that.
Google Maps routed me on to a street that was closed due to construction, Apple Maps was smart enough to route around the construction.
I expect general parity between Apple and Google Maps, I had not expected Apple to have better data.
