It does have some warts but is the best out there. I believe the code review market is very ripe for disruption (especially for software hosted publicly on sites like github).
I have similar sentiment. Use a lot of Atlassian tools over the years and I am constantly bitching about various issues... eventually someone says "ok, find something else that's better"... and I can't. Not for lack of trying... there are lots of competitors... but they all are lacking.
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.
