If you are a professional writer – i.e., if someone else is getting paid to worry about how your words are formatted and printed – Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish.

I’m an Emacs user and I’m proud of the fact. I know my reasons for using it (and loving it) for many years now. But many people don’t. I often get asked by various people the same question - “Why should I use Emacs? What makes it better than Eclipse/IntelliJ/vim/etc?”.
