The downside to Waze's system is that it's reliant on other active users on the road. So if you're the only Waze user for hundreds of miles, the app has no idea what's going on up ahead. Fortunately both services let you save maps offline for later use, though Google Maps is more upfront about it.

Waze includes user edited maps, which being a map editor is a fairly well thought out and easy-to-use process once you get the hang of it. When driving with the app, Waze also alerts you to any incidents (Hazards, Accidents, Police, Speed Cameras etc.)
