Yes, but who said otherwise then?

Oh OP made it up. Nvm. They write themselves that it is a notion alternative.

None of those tools are editors, right? They all try to be a notion alternative, which is also not an editor. There is basically 0 focus on typesetting.

No, because with the above you can have rich objects in databases (for example, a dynamically updated list of medical events, each with all the attributes I want, attachments etc.), and almost arbitrarily deep nesting of databases. The idea to have databases with pages is one of the key features that made notion successful. It allows to structure knowledge without duplication, in addition to provide some other no-code features.

Spreadsheets are not even close.
