I'm actually starting to do this but with Obsidian. I love notion but one of my issues with it (and this is purely on principle) is that you don't "own" your data. This got me thinking, what would happen to my data in 5-10-15 or 20 years down the road? My solution to this is to have a bunch of markdown files in a git repository and use obsidian to manage it. I assume that in the next 5 years something better than Obsidian will come out though the idea is that is really doesn't matter in the end because the data stays the same.
I've extensively used both. The problem I have concerns this part:

Something better already is out, and the data has already changed. A ton of the power of Notion is in the structured formatting of note metadata; Notion calls them Databases. This is the core of a lot of the produtivity-hacking snake-oil that these YouTube videos sell, but there is something to it. Markdown doesn't have a correlate. Nothing even close. You physically cannot represent in markdown what is possible in some of these Notion documents.
Indeed, as long as we can export data I wouldn't mind too much. Worst case you can write your own tool to represent the data in a visual format you desire. I think the columnar structure of Notion (which collapses on mobile) is quite neat.
The only thing I'm scared of is I've started writing a book (in Notion), and it would be a shame if something happens to it due to unrecoverable data loss...
