Fibery on is a detailed, feature-by-feature catalog of note-taking apps. It allows for full-length head-to-head comparison too. While Fibery obviously is not positioned as a note-taking app, it definitely fits the bill and have some outstanding related features. Currently it is not included in the catalog, being under consideration. Please vote for it if you think spreading a word could be beneficial. I am not sure voting has big impact though. There are established apps like Capacities or Walling still under consideration.
