I am not talking about the command set, I am saying basically, that to
use git you need to understand its inner working otherwise you are
pretty much lost, that's definitely not the case of Mercurial nor bzr.

I don't know if you are serious, but do you really think that Git is
extensible ? I would rather say it got a pseudo extension mechanism :
scripts that operate on the repository.

And btw, it is technically possible to extend bzr and Mercurial using
external tools written in other languages that operate on the
repository in the same manner as Git. But I would stay away from that
: it is just plain ugly.

git-svn dcommit ? anyone ? In fact git-svn as a program should not
exist in the first place if git had a serious extension mechanism.

Please consider trying both bzr (>= 0.91) and mercurial, and judge by yourself.
