Jira can be highly customized. I find it easy to use for day-to-day. I also have to deal with Jira with a subsidiary company, and their Jira is completely different, but it works well for their use case.

The reporting is a whole other issue. I don't use this, but my PM does because upper management keeps changing their reports and my PM has to keep linking and organizing. But as a developer, doing spring planning and burndown charts work quite nicely.
