cogito
 - Not practical
    * the lots of little files doesn't scale well with the size
      of the portage tree
    * In addition, git only allows checkins from the project parent.
      A deal breaker in my opinion
cvs
 - Branching sucks
 - Merging is terrible
 - File deletes are bad
 - Atomic Commits
svn
 + Atomic Commits
 + Merging/tagging/brancing is a simple "copy" operation
   http://svnbook.red-bean.com/en/1.1/ch04.html
 + lots of benefits
   http://svnbook.red-bean.com/nightly/en/svn.intro.features.html
   there is more I'm sure people can come up with
 - 2x Drive space
darcs
 - haskell dependency
 - doesn't work on some architectures
   - IMHO, deal breaker
svk
 - not a contender, it is subversion.
   if someone wanted to use svk with the subversion tree they could;
   it is transparent to any other.
