I guess I kind of agree with your disagree, but disagree overall!
The UI in LibreOffice feels quite clunky and outdated and never seems to have been given any thought since the OpenOffice days. But Google Docs is so feature poor that I'd rather live with LibreOffice's UI. Especially as you can adjust to the latter after using the software for a while.
Have you tried LibreOffice's ribbon interface? It is similar to the one on Microsoft Office. You go to View > User Interface and choose "Tabbed". There are 7 different variants available.
