It's not bzr's fault that someone had the bright idea of setting up the server to serve the emacs' repo via a slow "dumb" protocol (sftp). I've been using mercurial for the past 2 months and Bazaar for the past 4 years. My personal preference is Bazaar as it handles my workflow much better than Mercurial does. Mercurial seems to encourage a "commit everything to trunk in a linear fashion" like svn. Named branches seem to be the only way to ensure that a merge comes in as a single commit rather than a "fast-forward merge", but they're discouraged for some odd reason. Maybe there are some extensions that make mercurial easier to use in this regard, but I haven't looked too hard. Maybe that's not a big problem for some projects, but for me, I like to know when a particular feature was landed in trunk, and what commits are related to it, so when I revert a change, I'm only reverting a single commit rather than having to weed through the tree to find all the commits that need to be reversed. And if I'm "doing it wrong™", please let me know off list how I can improve things. I have not used git yet, so I can't comment much there other than that the impression I get is that it's probably the most capable system out there, but where it still has a ways to go is usability. I hear that's getting better too, but this git-cheatsheet (http://www.ndpsoftware.com/git-cheatsheet.html) still confuses me. John Szakmeister, who is a Subversion developer himself, has a good comparison of svn, hg, bzr and git: http://www.szakmeister.net/blog/2011/feb/17/choosing-new-version-control-system/ Long story short, his company went with git.
