Jira requires a person to tailor it to your org. It can be pretty good if you have people who configure it correctly and have a workflow that suits your team/org, but that's kinda the problem: making Jira be good is a full time job. Confluence is just a terrible experience overall. Terrible editing, terrible browsing, terrible search. I've used both at multiple orgs, I've seen Jira be good, I've never seen Confluence be good.
