Obsidian is good, but emacs UX and power are on a whole other level if you invest in it. I recently integrated and extended a presentation mode for my org files. It allowed me to reuse all my emacs goodies when creating slides, and all the content is easily searchable and linkable. It is even a great UX when presenting; I could very easily jump between slides to show the relevant slides when questions came up. It’s exportable to beautiful HTML, too.
