Google spend much time organizing the name of the cities and road in a particular way. Now Apple has another way of doing it, the maps at higher level show less information. Some city name are picked and some are not, but at a closer level, the cities are there. Their algo to find what to show on the map is just different from Google. I'm not saying it is better, but different. I am pretty sure the same comparison can be made between google maps and let's say bing maps.
