Apple Maps are improving, but they still suck. I have read a lot of complains about them from users in U.S. and Europe. Imagine us in Latin America.
I live in Bolivia, and all my neighbor does not exist for Apple Maps. Here a comparison of Google Maps vs Apple Maps of the same area.
This is Google Maps
This is Apple Maps
As you can see, there is a lot of difference, also Apple Maps are unable to find a route between two points in my country. While Google Maps does an excellent job on that.
Google is preparing its maps app, and I am really waiting for it, and hoping that Apple authorize it in the market. I'm sure I'm not alone on this.
