I deleted my original comment, because I realized after the fact that you specifically cited "project management".

I'd just say it depends on the size of your org. Depending on what the projects you're trying to manage look like, the Atlassian tools offer some features that _really_ help. Prior to adopting Jira, teams were using some combination of Trello and Asana. The lack of any shared structure between teams made cross-cutting projects very hard to reason about.

Jira definitely has warts and annoyances, but it has a solid API and the JQL language for querying issue data is incredibly useful.
