I have no opinion on Apple Maps, as I haven't owned an iPhone since before it was available. However this, anecdotally, is definitely not my experience with Waze. Unless an accident happens (or additional traffic for some other random reason) on the route while I am on it, it is almost always perfect in its prediction. There are a few routes for me to take to and from work, and I check Waze every trip for which one I am going to take. I have learned to never argue with the route it takes me. Every time I take the 'Google' route instead of what Waze wants, I regret it because I end up sitting in an extra 10-15 minutes of traffic. Its also nice to be rerouted off of a road if an accident happens part way into the commute. I happen to be one of the fans of moving instead of sitting in traffic though, so that could also contribute. Its probably also worth noting, its 45-65 minutes each way, depending on start times. Perhaps the distance / time affects mine over the author. I might actually start a table of what it does for me now though, could be interesting to see.
