You have to credit Apple for being ambitious in creating their own mapping app to compete with Google Maps, however a little testing by me recently shows that Apple has much work to do yet. As an example I asked Apple Maps to find the directions between my home and office and it came up with a circuitous route of 2.4 miles while Google got it right at 2.1 miles:
Next, I asked each mapping tool to find direction from home to Rolling Hills Community Church, once again Google came out on top saving me 1 minute of time by taking into account traffic congestion:
Finally, I compared mapping directions from home to Champoeg State Park, Google found a route 2 minutes shorter than Apple:
My first mapping app was MapQuest, then Google, so based on these results I continue using Google Maps. Maybe in a few years Apple Maps will improve enough to consider using.
