To clarify, I expected that to be it but when I took the Apple Maps route, I didn't find any significant traffic en route and arrived at the estimated time that was way earlier than Google's.
It seems like you live in Toronto so I can be specific: I was leaving King/Spadina to go somewhere in North York. Google Maps sent me along the Gardiner to the 427 backtracking considerably, then up to the 401 and along that to my destination. Apple Maps sent me up University/Avenue Road all the way to my destination in 3/4 of the time.
People treat Google Maps as perfect. I rarely hear anybody complaining about Google Maps' quirks but when Apple Maps has the slightest imperfection, it's piled up on.
I know that Apple Maps is flawed in certain regions but in Toronto, it works incredibly well so I have little to complain about.
