    Very good tool IMHO: I have been using it for years, both as a visual diff and it integrates well as a 3 way merge tool for version control systems not just perforce, e.g. git , svn, bzr. Which is its primary purpose. AFAIK its QT based, only ugly if you think QT is. Default UI uses RedHat default laf, and Crystal icons from Everaldo
