I am beginning to like it and I really do not want any more google apps on my phone, so I just use it. Really, the only thing that is unusable right now are cycling routes. Every single time I select "bicycle" it just displays me that bike routes are not available - this works fine in Google maps.
Overall I find Apple maps to be much cleaner and intuitive. There is not so much stuff in the way when you open the app and quickly want to search something. Google has done a great job cluttering their app with every update to a point it just got me frustrated - and so I stopped using it.
