Not sure about data, but whether I like it or not my days also contains a substantial amount of time with both Microsoft Office and LO/OO. At the beginning (this was some years ago) I forced myself to use OO over time to get over the initial hurdles. My employer jumped on the ribbon bandwagon quickly, so I have had daily exposure to it for years now. I hate them, I really hate them. They occupy way to much space vertically, a show-stopper in itself. More annoyingly, I find them hard to navigate. Even very frequent operations are spread across different ribbons, forcing me to navigate them. I can place about three rows of LO icons (haven't measured, but I am surprised if I am far off here) with the same space occupied by one ribbon, but two rows are sufficient to cover all of my the most common operations. Again without checking, I would guess you need about three ribbons to cover two rows of LO icons.
With respect to menus, just about any other software in the universe uses them. Hence, the data is overwhelming, we all know how to maneuver them. We all know how the shortcuts go.
As for most people MS Office is but a tool, my day is filled with other stuff too, so there is a limit to how much time I want to spend learning how to use ribbons effectively. After years with ribbons, I still prefer the traditional ui, and I am pretty sure I am more productive with it. On my laptop I avoid MS Office totally, it takes too much screen to be useful at all (I know I can hide all the functionality, but kind of defeats the purpose).
