Well, as in the other post it depends what exactly you want to do with it…
I mean technically even [insert literally any plain text application here] would suffice for this. So basically you’re looking for an application with feature X, where you don’t know what X is yet.
That aside, if we’re going to assume you might publish your writings as well, you might look into something that supports Markdown, so you can post it easily on any forum without having to do formatting - because you already have it.
For that, maybe a code editor like Atom, VisualStudio Code, even Brackets could be nice. They probably all have some kind of extension where you see the Markdown rendered alongside what you’re typing, which should help greatly.
Of course Markdown has its limits, but there we are again with “what do you need”. If you want to do just texts and lists this is fine, if you want something like a mindmap then I’m out, cause I never used that.
OneNote can do a lot, but frankly I only type stuff and use the check-box lists occasionally. Needs differ though.
One additional pro of Markdown: There are a ton of Android apps (e.g. Markor) you could use for writing down ideas on the go, and sync your markdown directories so both are always up to date.
From your other post it seems you want the “perfect” tool from the get go, and I get that for the editing part, because working your way into the flow of an application takes time, but honestly for something like notes… don’t make your life complicated. Get started, and when you’re at the point of “I would like to have X”, you can look for a tool that does X as you want it.
