Pros
Pro Blocks offer incredible flexibility
The basic unit of organization in Notion is the block, which can be a chunk of text, an image, a bullet point, or even a link to another page. Each page consists of these blocks, which can be easily reorganized, moved to other pages, converted into other content types, or generally manipulated in many useful ways. Because of blocks, restructuring information in Notion is way easier than in any other wiki or notebook app.
Cons
Con UI makes it easy to unintentionally mess up stored info
Notion's UI is so simple that at times it can become easy to accidentally delete a page or mess up its contents. Thankfully, they make it really easy to recover deleted pages, and the version control makes it somewhat feasible to recover deleted content.
