Yet another Mercurial-stan convinced of their "rightness" in the face of the overwhelming popularity of the alternative. Just blame "Github" and the "cool kids" for picking the "wrong thing".
I used Mercurial for a while when I was still also learning Git and migrating from SVN. It had serious UX problems and Git just "clicked" for me in a way that Mercurial just never did.
Perhaps I just wasn't smart enough to see the genius of Mercurial.
