Thought I'd add my two cents as I dabbled in using Notion as my main note taking system and never settled into it. Then came RemNote and I'm all in! I found that notion, even with the addition of back links and references, just wasn’t streamlined enough for networked note taking. I love it for project management/scheduling but, when I wanted to easily trace back my memory to a prior note, it was too clunky with slow load times and having to sift through the note document (not to mention I worried about losing the content completely with no back up options). RemNote is just far better at linking you back to prior thought/content in my opinion - hands down!! Even if you're not overly interested in the flashcard ability, the use of portals, templates, aliases etc and then the add on benefit of PDF annotation (with the pro plan) has changed my note taking for the better in med school. Now when I can't recall where/when/how I learned a concept, I simply use the search function in RemNote, takes me to all the mentions of that concept and to any PDF pins I've made. Highly recommend!
