At a first glance, interdiff yields more intuitive results if it works, but it may fail if the two patches differ to much. I need to play more to see how useful it is in real world examples. I did not know interdiff before. At this point I'm not convinced that interdiff is exactly what I have in mind. For example it doesn't show differences between commit messages of two git patches.
