the choice of distributed version control system

Reading about mozilla's move to mercurial, it's still not clear to me which one is best: git, mercurial, bazaar, monotone or darcs? I've happily been using subversion for quite some time, but now I feel a real need for a distributed vcs. It also feels conceptually right.

One good point made in the reasoning for mozilla's move is that it's not a disaster to make the wrong choice; all of these vcs' contain all the information necessary to convert between them. For me, win32 support is an issue, and I need a plugin for trac. Analog to TortoiseCvs and TortoiseSvn, there should be a TortoiseGit, TortoiseHg, TortoiseBzr, TortoiseMtn and TortoiseDarcs. Uhm, wait a second, there is a TortoiseDarcs! A TortoiseBzr seems to be in the works. The other tortoise's pop up on google, but with nothing substantial.

So anyway, for each of these, you can easily find people who are passionate about it. But I suspect that that's just because cvs left such huge scars on everyone. It is high time for cvs to be erased from our collective memories and start being picky about the features these new (distributed) systems have to offer.
