Yes, kind of. The true advantage of Org-Mode is the extensibility, which comes from it being implemented in Emacs Lisp and living in Emacs. That's how people have been able to bolt on so many useful things on it like Babel (not the JS thing) and the export mechanism, and how you can have many types of useful links both inter- and infratextual. It's so easy to link somewhere in the document, in the file system, in your mail boxes, and to some piece of code etc. Editing functionalities help, but Markdown too has similar stuff (spaces before code, > before quotes, etc.). The actual benefit of Org mode in emacs is that I can really easily program it to do what I want. I use the same tool to digitise and store my prose; create PDF documents with citations and whatnot; store all my personal and lecture notes; keep, interact with and browse my agenda; keep executable notes from my shell sessions with links to documentation and screenshots etc (a la IPython); and publish my website; and all these documents are easily hyperlinkable, and anywhere in them I can have to-do notes that I can easily have pop up in my agenda, and then export to ICS or CalDav to access them from my mobile phone (there are MobileOrg and Orgzly for viewing documents on mobile, I use the latter). I don't know how you can do such things in another environment than Emacs, while both providing the same interactiveness, the same extensibility, the same customisability, and remaining resource-efficient on the computer and using only a single programming and configuration language.
