I only go back to Waze when I need the "plan a drive" feature, where you tell it what time you want to arrive, and it tells you when to leave.
Here is a screenshot of the feature I'm talking about: https://techcrunch.com/wp-content/uploads/2016/03/waze-plann...
Basically, I know I want to go to A, but I'm not sure when to leave, I just know I want to avoid as much traffic as possible, so when should I leave? The feature kind of answers that.
With that said, I do prefer waze’s graph showing traffic changing over time to help decide when to leave
