There are a few new features over the last 5 years...

  * Merge checks
  * Build status (finally...)
  * Audit logs
  * Inline editing

Nothing that keeps it above Github, but they always seem to maintain feature parity.

/not a bitbucket shill

//just don't like inaccurate comments.

If you're only comparing Bitbucket by itself to Gitlab then you'd be correct.

If you do a fair comparison and compare the entire Atlassian suite to Gitlab, then you see that the Atlassian suite is far more powerful for most enterprise use cases, which typically involve highly customized workflows and reporting in Jira. The integrations with Jira, making it incredibly easy for higher ups to follow overall progress on software projects that are tied to complicated business processes with long lifecycles, to help understand where the enterprise is in its lifecycle on any given issue and reprioritize resources to prioritized tasks as needed.

Nobody has an issue tracker that really competes with Jira in this space, least of all Gitlab.

I very much doubt big enterprise clients use the services at bitbucket.com. Standalone is where it is at, and BitBucket (previously Stash) is a worthy competitor to GitLab (which was pain to setup just few years back). Big companies usually don't move at the speed of javascript frameworks.

I don't use it much, or rather at all so I don't have much to say. GitLab has a more appealing UI than BitBucket (likely more features too), they have a great team who hang out here on HN and respond to feedback very quickly, they are actually focused on just GitLab while Atlassian has a lot of projects to work on, and their rate of development is much faster.

Trello, Bitbucket and Github are mature products. Github Projects is MVP.
