I agree with you.
There are two things: features and UX, and app technology.
Notion has powerful features that is not in Evernote. I'm able to manage my stuff using Agile method for the first time just like I do in my software projects. And I can mix projects together in one board, something not possible on famous software project management platforms. It's not structured, yes. But this gives me the full flexibility to achieve that. For the editor, after using it as my primary tool, I found that this editor is the best editor for professional. Simple, powerful, and standard.
For app tech, I sticked to Evernote because it's native. After being web-based, they are equal, and thus Notion was worth a shot.
Still Evernote has its own uniqueness, but I don't think it's worth paying the money anymore.
