Disagree; Jira + Kanban is if anything even worse. Since Jira is such a pain to use and Kanban doesn't have any requirement for estimation or timeboxing, people will write one ticket that says "do everything" and work on it for 6 months. While admittedly avoiding Jira for 6 months at a time is good for the soul, when you put your head down and work on something with no context for 6 months you usually end up making something that wasn't actually wanted and has to be thrown away or drastically reworked, which ends up being more soul crushing.
