I also switched my dev team to it once it grew sufficiently large (at a now acquired startup). The primary thing it enables is actually having a structured conversation about your changes, and having several _revisions_ of your changes through which the reviewer can navigate, much like Gerrit or its progenitor - Critique. Once you experience that, there's simply no going back to anything else.

The UX makes me want to gouge my eyes out with a dirty spoon, but it's still worth it, in spite of the UX. I'm baffled why MS/GitHub can't just go ahead and rip it off at this point, to replace its own utterly atrocious PR review workflow.
