Confluence vs Zendesk

The only drawback is that it's not very user friendly, however Atlassian does provide good tutorials, and I take advantage of that.

Confluence has most features needed for my work, but it can be difficult to format code and mathematical equations easily.

The navigation within the internal system can initially be a bit difficult (i.e. the naming of the tabs are not always clear), but once you know where to click, it's not too bad.

Background workflow good but still not as flexible as others, Salesforce service cloud for example.
