I am actually a big fan of Arcanist. It rather simplifies the Git workflow management. You simply develop new code in a separate branch from master, and use `arc diff` from said branch to start a Pull Request (called a "diff" in the Arc world). No need to use `git push` and manage upstream branches, simply rely on the diff abstraction. It has many great features including `arc diff --preview` which gives you a link to a preview of your PR so you can see what it looks like in the browser (much better than `git diff`). Of course, there is a bit of a learning curve and most engineers already know the standard git workflow. That is a disadvantage of course, but only in the short term. If it's a short project, then I would recommend against it. However, if you're in it for the long run, arc is great. I feel like the other points (CI, lack of support, etc.) much better show the weak points of Phabricator versus GitHub or GitLab.
