I tried wholeheartedly to migrate to using Joplin from apple notes so I could use a native client on more platforms than my phone + laptop, but it was frustrating in so many ways. S3 storage syncing frequently broke on the iOS app, simple auto-formatting insidiously defied my expectations, and it was very difficult to keep things organized without very explicitly labeling my notes (which I don't have to do with Apple notes, as you can see a preview of the text contained inside of the note). I'd love to revisit joplin in a few years when I have more time to tinker or contribute to the project, though.
