Not because vim vs nano vs emacs etc. Just that plain text is not enough.
I want to be able to encode more of my memory and context to my notes with a minimum of fuss, and therefore want to embed images (gasp!), tables, hyperlinks, and even file or sound embeds in my documents.
Yes, open simple file formats are better than closed complex formats (and doing text vs binary formats has something to say for it as well).
No, I don't like that Onenote's .ONE file specification is super complex and therefore only semi-open.
But I'm not about to lock myself into a DEC dumb terminals 80x24 limitations where I have to learn some greybeard's key bindings for everything, all for the privilege of losing all my ability to embed multimedia combined with said gatekeepers tut-tutting me that I should just make a link in my terminal to the local image file, nevermind that you can't copy/paste an image into a bash terminal and have the file be saved to that directory (ok it probably exists but is some obscure something).
So I watch Xournal++ very closely, specifically [this issue](https://github.com/xournalpp/xournalpp/issues/937) because it will have the total package, multimedia embeds, ink support, text support, file embeds, all in one file that I can syncthing save to wherever else I like.
But until then? Onenote desktop, sorry but not that sorry.
