My anecdotal contribution. This past spring my daughter's soccer team moved up in competition level. Instead of playing at the same field each week they now had to travel to different fields around the county each weekend. After the first couple of weeks one group of kids had gotten to each game the 30 minutes prior they were suppose to and a different group of kids arrived just in time with the parents complaining about traffic being worse than expected. After discussion on the sideline we identified that the latter group was using Apple Maps and the former Google Maps. Each time Apple Maps had directed the parents a way that would appear to be faster based upon distance and speed limits but in reality were slower because the roads in question regularly have slower traffic than the posted speed. Google Maps avoided these choke points which tells me that for some areas at least Google still has better information available or utilizes the available information better to calculate routes. The Apple Maps parents switched to using Google Maps.

I believe Google Maps uses Waze's traffic data now, so crowdsourcing keeps it very up-to-date.
