Yeah, I find the similarity most striking with LibreOffice Draw vs. LibreOffice Writer. It very much feels like Draw is just a superset of the features of Writer.

There is certainly some differences, though, e.g. text doesn't automatically overflow onto new pages, text boxes don't automatically increase in size, things like that.
Everything is a lot more static, which is great for layout, and less great, if you just need to type out some text.
