I never really got to understand why this is so important personally,
I can just affirm that is is just a matter if habit. I was used to
having all the branches in the same repository while I was using
Monotone (few years ago), when I later switched to use bzr I got
slightly confused, but now I find the 1 branch / directory far more
user friendly, it even encourages people to have a branched
development workflow (which is what we want don't we?), because all
the branches are visible, they are no longer just mere "live tags" as
in git.

I completely agree with you concerning this, there are many drawbacks,
and the most important one to me is that many users are used to
centralized workflows. However there is a very nice feature in bzr
that removes this drawback: bound branches.

Git imho is a good repository format, but the required frontend to use
its power efficiently whil remaining user friendly is not there yet.

bzr-svn in the same way as hg-svn have been plagued with the
python-svn binding leak problems, also bzr-svn and git-svn are not
really comparable, since git-svn is a separate tool with its own
command set (correct me if I am wrong), while bzr-svn is a plugin that
adds svn support to bzr, and thus allows you to use transparently all
the available bzr commands on your repository.
