I haven't used Notion the last couple of years either, but there was a multi-year period where someone at each of the companies I was at would champion it, convince someone high enough to transition the team to it, and it would slow the team down so much. There was a joke at one point amongst coworkers that it might not be bad subterfuge to get someone hired at a rival in order to introduce Notion there.
Anyways, I think Notion has a learning curve that is a little longer than one expects. I can believe that with some dedicated learning time I could be turned into a believer. But I also distinctly had the impression that it was one of those things where it saved a ton of time for a few narrow-visioned people (the people who championed it), but added meaningful time to everyone else's. Those people were largely project managers or operations folks, and transitively the leaders they reported to. It heavily threw the switch towards "legibility" over reality.
It's like when someone new to a messy project, creates a spreadsheet, and says, "Let not overthink this, everybody just fill in your project details in your row". If your work, which you are the expert on, doesn't fit nicely into the person's columns, it's not easy for you to fill out. Meanwhile, the person who created the spreadsheet, gets what looks like a neat and orderly answer to everything. All the messy things—which are or at least have in them the correct status of the thing—will be masked under a clean and simple, but rather incorrect, thing. That spreadsheet will also travel far specifically because it's neat and therefore portable. There aren't a bunch of "it depends" in it.
