Question Ranking
Pros
Pro Does a great job with both notes and to-dos
To-dos in Notion aren't just dot point lists. You can drag and drop them into columns just like Trello (Kanban style), you can have sub-tasks, and you can easily mark things off as completed so they are no longer in your way. Notes are also powerful, with proper formatting and ways to manage and search for them, which makes it a great Evernote alternative.
Pro Flexible contents storage and organization
You can upload files and embbed online stuff in any hierarchical structure using pages, toggle lists etc
Pro Awesome for wikis
You can easily start writing a bunch of web pages, share it with co-workers and choose whether to publicize or keep your contents private. It's also easy to hyperlink pages.
Cons
Con Designed for teams
As an Evernote alternative, this was mostly designed for individual use, so if you aren't a part of a team a lot of the functionality of Notion is pretty useless for you and might result in a more cluttered interface.
