Overleaf is a collaborative writing and publishing system designed to make the process of producing academic papers much quicker for both authors and publishers, from Writelatex Limited in London.
Emacs is best utilized on a Unix system where it can be easily installed and accessed. It allows for quick editing of files on a system whether you are accessing it locally through the console or remotely via an ssh connection. Once users familiarize themselves with the Emacs shortcuts, it becomes a pretty efficient text manipulation program. On a standard Windows computer, it is less likely to use Emacs for code editing, especially if you have a local repository on your host machine.
Overleaf is good to use in a lot of scenarios where something is to be written as a group. However, I believe that it is only good up to a certain amount of people working on the document at once. While I am unsure when it becomes too much, I got no doubt that there is a limit for when it is that good. Though normally, our group size of up to six people has been fine to work with in Overleaf.
GNU Emacs is a text editor that can do almost anything that you want to do with it. It is fairly easy to extend the functionality using Emacs Lisp with a large library available.
It can be easily customized using themes as well as custom code to change the look and feel as well as how everything works.
Emacs is old, so it's a little crufty and not too easy to pick up and start using. There is a community package called Spacemacs that simplifies a lot of things that you do with Emacs. It is probably better suited to beginners.
Sometimes, the choices that were made to integrate certain functionality change the basic models for that functionality. This is seen primarily in the version control system support, where multiple version control systems are supported and "unified" to a standard Emacs-y way of doing things. This can be confusing to the new user not familiar with the Emacs way.
Emacs has, as its foundation, a lisp interpreter. This means that the extension language for Emacs is emacs-lisp. Some people find lisp hard to understand and have difficulties writing Emacs extension code, or understanding existing code.
Everything that you need to know about Emacs can be found on the internet. There are many Emacs "cheat sheets" that list out all of the shortcuts for Emacs. There are videos on how to use Emacs. Emacs is easily installed using the standard Linux package managers and can also be easily updated through them as well. There are tutorials on how to customize Emacs to your liking.
Of course, Vim is a good contender for comparison as well, so I'll include it. I find Emacs much easier to learn, which will help speed up productivity for newer users. It seems much faster than VIM and VSCode, especially under load. It's highly highly customizable, in ways other editors don't stack up against. Its lack of bloat also is a nice addition to a great product.
Overleaf promotes collaboration and has much better scientific formatting, which makes it great for research papers. It allows for much smoother and more professional looking documents, with easy to change and configure formatting. It is very difficult to insert mathematical formulas and long complex derivations in Microsoft Word, and formatting in Microsoft Word is also very finicky.
