Ask HN: YAML or Markdown for Personal Notes?

I've used, Evernote and yes it was okay, until I realised I do not want my data out there in the wild. This was maybe back in 2015.

Since then, I use Notepad++ for everything. Save things here and there and it's really unorganized. I feel shame because I am actually a mega-organised person...

So... I tried Obsidian. Wasn't my tempo.

Now I am at organising my notes by text file by the following format: /Notes/Year/Month/Y-m-d.txt

I am seeing myself naturally moving towards Marking-Down my notes, which I like. But it brings me to the question: which is better to use for future use-cases in terms of software and tooling?
