I will say in favor of the ribbon: it still fully supports KeyTips (a.k.a tapping Alt and then a series of letters to navigate a software menu). So much Electron-based slop software out there doesn't support any sort of keyboard navigation of the application at all.

I do find the ribbon somehow weirdly intuitive for navigating with the keyboard, but it was of course possible to navigate drop-down menus in the exact same way (Alt and a series of underlined letters) for years before that. And still is... When developers bother to write robust software.
