SInce you mentioned "unique" features, Emacs is the only programmable editor which works mostly the same in terminal and GUI mode. You can write extensions (in elisp) which largely dont know about the UI used by the user. So you actually can write UI-independent programs in elisp. I dont know a single tool that got this right.
