It would have been nice to also see the numbers for Bazaar, which seems to be #3 on the list of mainstream DVCSs. I adopted hg for $HOME a few months ago, and it's working great. This was after having used SVN for a few years for the same task. I might have chosen bzr for it's amazing attention to usability, but at the time it had some performance issues with 'log'. Although Git has quite a following, I just couldn't adopt it given its enourmous command set (140+ commands), and manual heuristics for when to repack.
