Thanks for your reply.
Ok, so how are the Micorosoft navigation maps compared to Google Maps navigation?
I have not used Google Maps navigation so I can't give you a detailed comparison. However, occasionally, my Uber drivers use it and every time they use it I get the shortest route even if it is the most congested one (since there is no traffic information in Google Maps in my area yet). The same is true for (Bing) Maps... but Bing Maps offers at least four different routes which can be chosen from. In other cities where traffic information is available, (when I was in Bangkok for example) (Bing) Maps seemed to adjust the route based on traffic.
As for "resolution", Google Maps is currently ahead - with more POIs (although a lot of it are also wrong - where I'm in), more accurate/complete addresses and more updated roads (even roads that aren't there yet but are currently under construction are already there).
Of course, these are based on my location - experience and quality will vary across regions. But if you would let me choose between Google Maps or (Bing) Maps, I'll choose Bing for two reasons:
1. it is the default of Windows Phones - who knows what those third party apps for Google Maps would do, especially just after the recent news on the fake Tweetium app that steals passwords, although nothing can be stolen out of location data alone
2. it is the same as Google Maps in terms of navigation routing (not because I'm a fan).
But if you add Waze into the choices, I'll choose Waze (for traffic).
