I have used Apple Notes since I got my first iPhone, there's still notes from back then in there! Mainly for quick lists and things I need to remember, ideas, shopping, etc. Haven't really found any issues with it.
For anything that I find lives in Apple Notes a bit too long I move it over to plain text and use iA Writer. I try to keep anything in Apple Notes as short term notes. Anything I plan to keep around as more (small) documentation I switch over to iA.
A few years ago I just got tired of trying out all these different notes apps. I figured I have iA Writer and Apple Notes and that works well enough so gave up trying every new note taking app that came out and haven't had any regrets.
Recently I tried out Notion and god it was awful. I felt I spent longer arranging things in Notion than I did working on things.
These days I find a more limited and simpler solution is better for me. I switched back to Things 3 a year or so ago as I found Todoist overwhelming after a while. Sure Things is more limited but I like that. It is basically a post-it note and I realised that is all I needed.
