Jira (hasn’t been JIRA for a long time) is great when you have proper Jira governance in place, with admins who say “no, you can’t have a new custom field, use this one with a new context”, configure good workflow transitions with validators and conditions, design appropriate create, view and edit screens (instead of using the same one for three separate operations), etc. The problem is always crappy administration, not Jira. Jira can be fantastic when properly managed.
