So why look anywhere else you ask.

The problem with confluence and Jira in general is that it is a product for large corporations and as such it is rather complex to configure and hard to maintain. There is a reason why average Jira admin salary is around 80k$ per year. It's complicated. Some of the addons may be clunky, Jira integration is mediocre at best. However confluence is a solid product. It has it's shortfalls but for the price it's better then many other alternatives, especially if you are a large enterprise and want a product to fit your corporate culture.
