I would far prefer an organized UI to one that tries to look clean by tucking away functionality under a hamburger icon. This is not to say that I insist upon menus. Since I never had much invested in Microsoft Office, I do appreciate the ribbon bar. It does a fairly good job of organizing and exposing functionality in an otherwise complex piece of software. Contrast that with GNOME's approach. It is rather difficult to design a complex piece of software when most of the functionality is hidden behind a single menu. At the other extreme, you have software that is somehow command driven. The interface can be kept clean by hiding away all of the functionality. (An example of this would be vim.) Yet that is not what GNOME is trying to provide. GNOME is a graphical interface that is supposed to facilitate discoverability. Discoverability will always be a trade-off between visual clutter or a reduced feature set. The only other option is to hide functionality, which is dangerous in a GUI.
