I use it, mostly for C++, a bit for Python, a ton of configuration languages.

There are dozens of us in the company, but only me in my team. The most popular editor around is VSCode.

There's not a lot of extra friction to use Emacs, the build system is well integrated, the debugger just works, the VCS is weird but the mercurial bridge is pretty good, and I always preferred using it in the CLI anyway.
