HipChat (unless you concede it was always bad)
What about HipChat don't you like? I know it can be buggy at times, but from a strictly functional perspective, I feel like it's ok, or at least sufficient for me.
Atlassian abandoned HipChat's bug tracker, and put up a fresh JIRA that they discourage you from using at several steps. That's one way to get the bug count down without fixing any bugs.
