I actually used to think that, but recently I drove from Lincolnshire, England to the South of France, used Google Maps on the way there, then used Apple Maps for the way back. Apple Maps was way clearer on which lane to be in, I felt like I had more time and notice for turnings etc and the voice just felt like actually having a person next to me directing.
I do however still insiticvly use G-Maps day to day!
When driving on the interstate, I use both Apple Maps and Waze simultaneously. This is because Waze provides me with alerts about any road hazards, speed traps or objects on the road ahead, while Apple Maps allows me to quickly glance at my Apple Watch for directions. Unfortunately, Waze does not have an app for the Apple Watch.
