It's like the vi or emacs of file managers. It's kinda hard to explain. It's value increases exponentially with the amount of customization you put into it. I polished my settings for years until I got to what I'm using now; but from then on, I never changed a single setting, I'm using the same settings file as for version 4 - current version is 7; It's got everything from different colors by file type to shortcuts for different folders, ftp, scp, crc verification, multiple file rename, viewers for lots of formats, tons of plugins...
