Atlassian a mixed bag
Jira is pretty good, and bitbucket is fine. Bamboo I've found frustrating as you can't prioritise certain builds, or trigger builds by a pull request being created. Fisheye/crucible is pretty terrible, it's very hard to get it to do anything and the UI is really confusing.
But there are very basic, popular feature requests being ignored, e.g. http://jira.atlassian.com/browse/JSWSERVER-9167
