@nomemory@fosstodon.org I'm using Doom Emacs because keybindings and commands are more discoverable respect plain Emacs.

Probably JetBrains IDE are more effective for programming in well supported languages. But, Emacs is the best or nearly the best for all other different usage scenarios. You feel always at home, because you can reuse all the tricks you learnt with time, between different languages and file formats.

Emacs is an interactive, Lisp-based environment, that is specialized for editing files. So you can extend and customize it endlessly. Also if you are not doing this directly, many other users of Emacs have done this. As consequences, it has a lot of functionalities, commands and packages.

In other words, there is no rigid distinction between an user and a contributor. The same cannot be said of Vim, JetBrains and other IDE.
