I'll help you with the reason: people who make Emacs are professionals at editing text. They understand what tools a good professional needs when working with text. The only editor that can complete with that is Vim. IntelliJ / MS / Eclipse products don't hold a candle to that, their authors simply don't know how to edit text well, and consequently don't know how to make tools to that end. It's the same reason why anyone would buy Hasselblad camera over, say, Canon. Canon is fine for a person who simply wants to take pictures of things they want to remember. Maybe even for a student in photography class. But, if you are going to earn your money as a photographer... well, you want a tool that you can rely on. If you go to the Moon and want your camera to work, you'll choose Hasselblad etc.
