I frankly don't understand how people come to like confluence. It's completely unintuitive to navigate, and the main way of avoiding the need for navigation- search- is completely broken as well. It frequently just does not find articles I know are there- I've habitually searched for the title of a page I needed without realising it's the one I was on, and confluence search told me it didn't exist! It's a pain to work with.

Bitbucket is just entirely forgetful, I'm not surprised you have. I found it slow and cumbersome to use.

I'll add another highlight to the atlassian experience: their CI product, bamboo. Also very cumbersome to use. To give one example, if you are debugging a pipeline and want to run just some tests, you have to individually navigate to each test's page and settings subpage to click it on or off- so with a healthy number of tests, you'll really start to notice those slow page loads! (I recommend automating this task with selenium).

I personally dislike jira, but as they say: democracy is the worst form of government except for all the other forms that have been tried from time to time.
