'Doesn't use Mercurial' was top of my requirements list last time I left a job that did use it.

Can you say more about how it's better than both?

easy to understand and use for everyone. you no longer need to spend tons of time teaching junior devs how to use git. By default mercurial also doesn't let you change history. There's no staging area or indexing before the commit. The gui and commands make total sense to the layman.

Git is definitely more powerful but causes more damage than good and wastes more time in most workplaces who are just looking for some simple version control and branching/merging features.

Not typing hg is the best part of my day
