I used Phabricator for 4 years in a previous company. I used also Differential, Arcanist (for pre-commit code reviews), herald, Maniphest, Paste among others.
Personally, I really liked it, except for the fact that the interface feels clunky and outdated. When I was leaving, the company was moving to GitLab mainly to use the "pull request" flow, which is not available in Phabricator.
