Are you sure you reside in Singapore? Because in this country, Apple absolutely pales in comparison to Google Maps. The competition is not even close. It wasn't close in 2012, and it sure as hell isn't close in 2016. I give credit to Apple for making the effort to issue improvements to their mapping data here, but they still have a very long way to go before they are even on par with Google Maps. The amount of missing POIs and incorrect geographical locations in Apple Maps are staggering here in Singapore.
There's no such thing as a perfect/totally correct map in this world. Google has been in the mapping businesses for years before Apple even ventured in, and provides me with correct data and places 99% of the time when I need it to. It seems like the guys over at Cupertino would rather invest their efforts in fancy Flyovers rather than going the extra mile to ensure their POIs and terrain/roads are accurate, which are arguably the more important aspects of a mapping service.
Apple Maps may be accurate in the US and UK, but they need to put in a whole lot of work into updating their data in my country before I will even consider using it. A whole lot of work.
