Which revision control system?
sh1mmer: I really love Bazaar.I love that it's distributed and I can version a local folder with a single command. I love the simple integration with Launchpad.net (which is annoyingly mediocre). I love that it's a single command which has all the inline help built in. I love the conflict management.However, people with a much better understanding of the details wrote comparisons with each of the popular DVCS currently in use. I suggest if you use another VCS you at least read the Bzr side (http://bazaar-vcs.org/BzrWhy).Specific comparisons:Subversion: http://bazaar-vcs.org/BzrVsSvn
