I'm guessing it depends from project to project? There are several Google developers contributing to Mercurial.

If you look at development at Google, you'll see most people on a perforce derived repo system , then groups like Android, chrome, Etc on git, then basically very few teams using Mercurial.

We do have some hg contributors like augie, but we have way more git contributors, includes git project Lead Junio.
