Notion is great in features, but it is just so slow and I find the editor hard to work with. Text doesn't flow nicely and it is clumsy to navigate between blocks. Some blocks are editable, some are stuck, etc. It is pretty hard. The speed gets me the most though. Maybe the website is actually better than the electron app, I always use the electron app.
Block navigation is definitely clumsy (maddeningly so), but I haven't had any issues with it being slow. Are you working with a lot of data on a single page?
