Yes exactly. I use LO because I use Linux and don't want to pay for Office on Windows until/unless I have a requirement. But I detest using LO, and your menu example characterizes my overall experience.

Chasing Office compatibility is a losing bet. I think they'd do much better tracking Office at somwhere between 50 and 80%, with sensible default/fallbacks, and spending the bulk of their time making LO the absolute best office solution on Earth.

tl;dr If you try your hardest to be like Office, you're going to suck worse than Office.
