The most important feature in OneNote, for me, is the "free-hand" writing feature on any PDF file. OpenBoard allows you to do so. It is also set up to take the whole screen with little distraction on it, so you can work and explain things to your students and collaborators.

It's a great way to take notes and organize your professionnal & personal knowledge. The mobile app makes it great to stay connected on the go.
Great for solo usage or small or wider teams in my opinion. Love the sharing & collaboration possibilities.
Beautiful editor and easy sharing. Just love it.


It's insanely fast (and written in Rust). Pen support. Pages and Folder support. Open-Source. Saves everything as file and thus can be used in a cloud sync. Has basic Textediting functionality (but not very good for structured Texts, more made for freeform drawing and handwritten notes). PDF insertion (no real annotation though)!
