> (opening/saving Microsoft office compatible documents, with layout, etc)

Not being Microsoft Office®-compatible does not make something not an office suite. In that case, there is (by design) only one Office® suite in the world

> not a wiki/markdown editor

I was wondering if you meant WYSIWYG editing as opposed to markdown editing, but then you say

> La Suite Docs seems a product more similar to Atlassian Confluence

which is WYSIWYG (the best web-based wysiwyg editor I've ever used, in fact; even if I'd never choose it for being a vendor lock-in that has shown they want to own your data by removing the self-hosted options, maybe with exceptions for giant enterprises idk but at least we had to migrate and it wasn't fun)

so then what are you saying? What makes an 'office suite' an office suite to you?
