I find Mercurial easier to use, even though I use git much more. I also find it harder to shoot myself in the foot with Mercurial - I've destroyed (but not lost) work with git quite a few times.

Many times this. Git reflog is an extremely powerful feature to fix mistakes. Any git user should at least in base understand what the reflog is and how it can be used for roll-backs.
