I use it and mostly like it. It is excellent at being a WYSIWYG, markdown-first, stream-of-consciousness, note-taking application.
The plugin ecosystem is sparse/immature, and the special features like PDF embedding/annotating are not very usable. It is difficult to set up sync properly (I self host Nextcloud and usually have to resolve sync conflicts whenever I switch devices). There is an Android app, which works fine, but the integration with the Android system (e.g. creating a note from a "Share" dialog) is... obtuse.
