OneNote or Confluence is the better comparison, for just writing text in but Notion has a more powerful data model. You can link a set of pages together through their attributes and view them through a table, kanban, calendar etc. It's basically a simple relational DB, which allows you to build information tools on top of it. At our (now defunct) startup we used it to do all our initial CRM and ticket management. We had all our customers in one table, and a different table of ongoing tickets linked to the first. We had similar setups for other things. As things started to scale we moved out to dedicated tools but having that capability meant that the initial version was much more accessible and useful.
