I always preferred Mercurial to Git, but now that Jujutsu is out there, I think Mercurial's demise is all but guaranteed.

If there were a reliable way to use Mercurial on a Git repository, it could live. But why bother when one can use Jujutsu?

Jujutsu took the best parts about mercurial and enabled these to be used with git and git forges. Once I had gotten used to jujutsu I didn’t really miss mercurial.
