It should be pretty obvious to anyone that's used both JIRA and it's competitors that it's a piece of shit. It's missing basic functionality that competitors have like live updates (I guess I'll just telepathically guess when my teammates have made an update and hit F5), it's got basic UX problems that everyone else seems to have solved just fine (opening outbound links in a new tab etc), and their new redesign appears to have done fuck all to make any of it better.
I don't care how many features it's got for BAs/PMs to wank over. If the basic usability isn't there, the devs won't proactively participate, which means they'll either be forced to (incurring a big hit to morale), or they'll use other tools like Trello or physical boards to organise instead, and you end up with multiple sources of truth and synchronisation problems.
How it's ever become so popular is a mystery to me. I wouldn't inflict it on a team of my worst enemies.
