I think the editor is random. Just read the kernel coding standards on tabs, indents, functions against keywords, using curly braces, etc., And it doesn’t matter which editor you use.
If you think that your choice of editor will somehow improve your code or help you get into the "zone" .. you are probably not ready to send corrections. git-send-patch exists because many people use many different editors.
If you kidnapped me and put me in front of any version of emacs, then you pointed the gun at my head and asked me to code, I ask you to just shoot me. I have nothing against emacs, in fact I still have one of the few surviving copies on the tape that I paid $ 50 to get a lot of time back.
Use an editor that allows you to focus, simple and pleasant syntax highlighting, good editing features, reasonable keyboard shortcuts .. a convenient gallery of snippets, and the rest is up to you.
Or, Chevy will improve your Toyota driving experience (I had to put in a straw man argument somewhere, after all, this discusses Linux development)
In the spirit of this, I'm going to re-mark your question now.
