Dreadful and woefully out of date maps. Google Maps is massively superior and will continue to be even more so, since they own Waze and Google Maps is the master project. It's a waste of time being a map editor too, it's dominated by a handful of authoritarian sad cases who prevent you improving the map using various methods. It's actually easier to improve Google's Map, which links back to the first point! RIP Waze, good idea but sabotaged by sad cases.
