Better Routing
Waze is considerably more adventurous and aggressive when it comes to getting you to your destination by any means necessary. While Apple Maps and Google Maps have generally tried to avoid annoying city planners by keeping navigation directions to main streets, Waze has no such compunctions, and will happily take you through a maze of residential neighbourhoods if it will shave a minute or two off your journey.
In fact, this is a feature that many Waze users swear by, since while most people are still using Apple Maps and Google Maps, and therefore being herded along the main roads, Waze users can be zipping along side streets to get around traffic congestion.
