I don’t know about that.

I think Libreoffice is easier to navigate than ribbon-era Office.

I think especially Gnome, but also Kde has better settings than Windows, which is spread across a new and a classical view (or more?).

I also think MacOS finder is worse than Windows/KDE/Gnome equivalents. When you strip so much away that people have to remember strange key combinations to jump/navigate to specific directories you have really gone too far.

And mobile UX (android and iphone) seem to me worse than any desktop system. Nothing is consistent (sharing data between apps), nothing ever seems settled (settings move around in the central settings apps every few releases).

We could argue in depth. Let me head it off a bit - taste is absolutely a thing, but consistency across releases is evidently a good thing unless you are constantly in a situation where your existing userbase is dwarfed by the prospective one. There’s a reason we hang on to diskette icons, don’t change from desktop to metro to ios style desktops every release and so on.

Last point: OSS software can be misguided, but it never seeks to bamboozle the user to make some corporate goal succeed. It won’t nefariously stuff files on a cloud or actively make it hard to export data or be incentivized to NOT interoperate with devices or programs shipped by competitors.
