Planners

Do any of you use planners for your classes? I bought a really great one because it seemed like a good idea to be able to keep track of everything but I realized that Canvas has a calendar built into it with all of the due dates so now a physical planner feels redundant. So I’m wondering if I’m missing something?? lol what kind of value are you guys getting out of your planner?
