In the DC area enough people have this kind of intelligent routing that Waze seldom saves me much time. And not all of it is intelligent, Waze-style routing; a lot of it is just that people know shortcuts. Even when it claims to have time savings at the beginning, usually it eliminates those time savings from its estimate as I actually drive. Sometimes Waze gets a shortcut for me that actually saves maybe three or four minutes...but at the expense of driving down dangerous roads and making numerous turns. Typically it's not even worth it. About the only time Waze is worth it is when there is an extraordinary event, such as a very bad wreck or a closed road. In those circumstances rerouting can save time. At least Waze is up to date. Apple sometimes gives me impossible routes (e.g. illegal turns) and has some street and highway names that have been out-of-date for at least six months. Google on the other hand has an infuriating way of asking me to confirm reroutes that supposedly save me time, and giving me only a few seconds to do it. But Waze has a muddy, horrible interface. All these services have flaws.
