We are migrating from Clearcase to another VCS (probably either SVN or Mercurial). For companies that have made this transition, what factors did they find important in sel
Third party support. Does the system have a mature SCC provider for Visual Studio? (SVN yes, Hg's not mature).
Eclipse? Both have good support.
Are your developers used to being command-line commandos? Then third-party support / plugins may be a non-issue.
