Jira -> Offers structure for bug findings, requests, ideas. Confluence -> Permanent place for information.

Slack is greatly helped by integrations with tools like this. Otherwise you would only have chaotic discussions and then try to find messages in Slack to remember things.

I'll grant that the three are better than Slack alone. I guess.

But Jira is not good. Likewise Confluence is not good. It's more like bleeding out slowly rather than all at once.

What would be better? I don't always love GitHub, for example, but it hits these use cases in a far more effective and productive way.

I think you’re missing the forest through the trees. I like Jira for simple request processes and tracking projects. Confluence is nice because you can making a living document that is constantly updated. I see huge benefits using them vs not using them. It saves organizations a huge amount of time for knowledge management. Slack, Jira, Confluence are much better than using email and Sharepoint.
