I mean, I get what you are saying. But the extensible nature of Emacs is years beyond what other editors typically offer. Can offer?
Elisp is not the best lisp out there, but it is still a really powerful language. And that the editor doesn't have any tricks/parts that you can't use as a user is huge.
Emacs can do everything but for specific tasks there's often something that specializes in that thing that's better (IMHO).
For example, when I'm writing C++ on Windows, I use Visual Studio. I do Python work in PyCharm. I use Sublime Text for Markdown and light duty text editing. If I'm working over an ssh connection, I use vi. If I'm writing a letter, I'll use Word or Pages. If I want a spreadsheet I use Excel. For slides I'll use Keynote or Powerpoint.
