I have used Mercurial at work for a few years about a decade ago after already knowing git basics (but only basics back then). It never felt "better" or "worse" to me, it was just a slightly different git. Its branch handling was a bit confusing compared to git's, but it was manageable.

One thing that perhaps let me understand git better later was how `hg pull` works actually like `git fetch` and makes more sense than `git pull`.

The team has eventually switched to git anyway.
