If you just want to do something quick or pretty basic, such as a crop or resize - the old/lite versions can be handy because they load a lot faster. (No waiting on extra plugins, tools, librarys, etc. that have to load.) Some people have both because of this. But if you're not likely to do an in and out jobber, then there's not much point for having the dated or watered down stuff.
