I hate the interface, but I find that it does a better job of routing me around bad traffic than Google Maps does (even though it supposely takes Waze data into account), and MUCH better than Apple Maps. So I use it every day for my commute. I ignore the other crap and just pay attention to the route it is sending me on.
If I'm actually navigating to a place I don't know how to get to rather than commuting, I'll tend to use Google Maps instead. The display is much easier to read while I'm driving. And Waze's traffic avoidance routing is very aggressive, so it can sometimes suggest really stupid stuff. On my normal commute when I know all of the roads, I can easily tell it's trying to get me to do something stupid and ignore it. But in an area I don't know well, I'm more likely to unkowningly follow an illogical direction.
