I switched from OneNote to Notion because OneNote never felt customizable enough for the way I work.
After using Notion since for a while, I honestly can’t go back.
OneNote is great if you want quick note-taking with minimal setup.
Notion is better if you like systems, databases, workflows, and building a structured workspace around your work.
They solve different problems, honestly.
Best advice:
Use both for a week with real work and you’ll immediately know which one matches your thinking style better.
