Well the ease of use sure wasn't their selling point. The only decent Atlassian product is Bitbucket...and they bought it and made it worse. Trendy design, too much configurability, and an "Enterprise" user base. If I could, I wouldn't use any Atlassian software.
Bugzilla -> Redmine -> Jira -> Trello/Asana -> Gitlab -> ...
I'd say things are slowly getting better.
