I think Phabricator is a really powerful tool for engineering teams, but when you try to do more cross-functional team collaboration, it's not as user-friendly as GitLab.
I used Phabricator at a previous company and miss some functionality, like Phabricator's ability to show issue dependencies in a more intuitive and granular way -- but at that company, we had a lot of trouble getting the Design team to use Phabricator, for example.
As OSS communities continue to onboard newcomers, they're faced with a generation that expects modern interfaces that are user-friendly. Having user-friendly tooling also helps promote diversity of OSS communities since it's easier to onboard people with all sorts of backgrounds, since the technical adoption barrier is lowered.
I think GitLab is a clear winner here since it's user friendly and designed for cross-functional team collaboration (GitLab dog foods their own product in all departments of the team, so you have HR, Marketing, Finance, etc all using it, in addition to the full product teams).
Full disclosure: I work at GitLab as the OSS Program Manager. Part of the reason I joined was because I feel really strongly about GitLab's ability to lower the contribution barrier and get more people involved in OSS.
