Had to do a trip from LA to Phoenix and spend a week in Phoenix over the last week and took the opportunity to use both Google Maps and Apple Maps. Here are my findings using both as directions and general lookup / planning for my driving.
Overall I am pleased with the improvements in Apple Maps. Apple has taken a big step forward.
Google still is my go to at this point - better traffic, more route choices, and Street View. I did find for directions both do a good job, usually. See note below on road closures.
Personal note: in many cases Apple Maps reminds me more of an atlas than a road map.
Biggest note: Apple Map directions would at times get the name of the upcoming street incorrect. This usually was a result of the street having a name and highway designation. I did not run into this with Google. The name shown / spoken matched the posted name.
Second Biggest note: Apple Maps failed to note a closed street And directed me right to it.
Apple:
Would sometimes incorrectly pronounce the street name. Is this tied to Siri?
Did not offer the best or good alternative routes. Could be the traffic accuracy was not up to par.
The Map view would not match the satellite view for some locations.
The satellite view was frequently out-dated.
I would see 3D to 2D to Blank in some map areas. Frustrating.
Liked the little touches from Apple Maps like identifying when to turn into a parking lot.
Google:
Would sometimes offer a route that made little sense. Like routing through a neighborhood with speed humps.
Liked the fact that traffic was usually spot on. Helped with planning.
The satellite view was generally more up to date in Google.
Street view is a definite boon over the offering by Apple.
Here are some examples of items I ran into.
Peoria Sport Complex in Peoria Arizona. I like the detail Apple applied to the map. I prefer the traffic information from Google.
I-10 and the 303 in Arizona. Both are okay however the contrast in Apple Map leaves much to be desired. Also note the road closure that is missing in Apple. Definite contrast in detail from the Apple view at the Sports Complex.
Once again Apple is like a mix of detail and misses. Planning a trip I would rather use Google at this point. Better driving information. Once again road closures are missing from Apple. I ran into this in the Phoenix area a number of times.
In Camarillo (Ca) here is a spot where Apple fixed it then unfixed it. The Apple Map version does not match the satellite either. (See below).
Any issues I noted were reported.
