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.

I know Google maps is a lot more detailed than Apple Maps, but I have been using Apple Maps since it was released in 2012 with iOS 6, and it has been quite dependable so far.
I remember once when I was supposed to go to a school for PSLE duties. The school had shifted to another location due to prime upgrading works. Apple Maps directed me to the correct location, while Google Maps brought my colleague to the previous location. Imagine her shock when she arrived at an empty location, not to mention having to rush all the way down to the correct site.
Now, this is clearly anecdotal, and it may well been a fluke, but I have been using Apple Maps for many years now, and it works pretty well for me. I like the Siri integration (doesn't always work though), the ability to plot a route home using force touch (for when taxi drivers don't know the way home) and the convenience of maps on my other Apple devices.
I guess Apple maps hasn't turned me off in favour of Google maps, and so I see no reason to switch yet.
