And mine...

I use heavily only bzr, and I see its limitations. I agree with Hans that
its main strength is nowadays Launchpad, although that fact that it is
easy to get going under Windows is a pro too.

Out of the 3 main DVCSs, I am also most tempted by hg, because I feels it
strikes the right balance between power and simplicity. However, for me
hg has a killer feature: subrepositories (or the forest extension,
previously): http://mercurial.selenic.com/wiki/subrepos

I work in many projects where the natural setting is actually a group of
projects evolving together. Sub-repositories are the natural answer to
this situation and a big pro for me because the reduce technical and
social difficulties with loosely coupled projects: better than a
fully-integrated repo as projects have some independence, but better than
separate repos, as it is possible to have comon history.

Maybe git has a similar feature. I haven't seen it yet.
