Besides the "modern" VCS's, I've used SVN, CVS, Perforce, and done both manual patch management and patch management with Quilt. I am sure there are some VCSes out there I would hate more than SVN if I used them, SourceSafe I'm sure, but I would honestly use any of those others I just listed before SVN again. Yes, I consider SVN to be a devolution of CVS.
