We use JIRA so by default we are shoe-horned into Stash/Bitbucket. I've used gitlab on my own and found it beyond easy to use and very reliable. I see gitlab people posting every once and a while on hacker news and they seem very interested in improving the product overall. Contrasted with Atlassian who seems to have no interest in improving their core product and only enabling new revenue-driving products or costly extensions. So thanks.
