I like Apple Notes. Exporting isn’t a big issue for me.
Overall I think Apple Notes is a lot better than it needed to be, and for a lot of people it can compete with and replace an app like Evernote or OneNote.
I prefer an app that has a dedicated inbox, however, so I can see which documents have not yet been filed, instead of needing to remember to file every single time. The inbox metaphor is why I use Todoist for tasks, SnapNDrag for screenshots, and why I like SnipNotes for notes (but as I’ve mentioned elsewhere I haven’t migrated to SnipNotes despite its having many nice features missing in Notes because it doesn’t yet accept PDF attachments).
(I also dislike being unable to see how many files are in each folder in Notes… but apparently that’s a limitation in my Mojave version of the app, but it’s available in Catalina, and the upgraded, synced iOS version that works with Catalina.)
