At least it apparently isn't doing well in our security audit and the security team is telling us G-Suite is in our future.
What I do nowadays is I iterate my texts in Org Mode, get the comments on GitHub and when we're all happy about the text, I import it to Notion and lose the writing to the black hole of Notion search forever. Now when they have a public API, I'm thinking could there be an Emacs plugin that could sync the text between Notion and Org Mode, that would let me keep my texts in version control? I guess that's just a matter of time...
The thing that Notion brings (which I found hard to work with in Gsuite) was that shared documents aren't owned by any one individual, and copies are far less likely to proliferate. So its good for shared documentation that an Organization needs, as opposed to two people collaborating on a document, which google docs handles fine.
The basic tables and cards and stuff are nice for many things but are not a substitute for sheets by any stretch of the imagination. And Notion has no analog for Slides.
