I feel exactly the same way. I always end up cursing Atlassian's software (specifically Jira and Confluence), but when I look for an alternative (primarily for Jira), I can't ever find anything that does it quite as well or attractively as Jira. Even with its problems, it still does what I want, and does it well. I would, however, love to see something try to compete with it. There are a lot of decent alternatives, but it would be cool to see a bit more competition.
