Usability of Linux desktop environments isn't perfect but at least the trend is steady improvement. The days of having to do weird stuff just to make some everyday USB device work when you plug it in are mostly gone. The software available for Linux in a few areas is now genuinely best in class. It's not always the same exact applications you might be used to but then that's true of moving between Windows and macOS as well.
My own experience of modern Linux is very different to yours. I don't think I've had to completely clean and reinstall any Linux system I use - desktop or server - for over a decade. Some of those systems have been through multiple full OS upgrades in that time but those were done in place and usually without losing anything (or gaining anything unwanted).
It's obviously not perfect. Some of the recent Wayland changes got released by some distros before some of the applications that do video calls were fully ready for them and that caused problems with remote working for example. But it's paradise compared to the danger of installing any modern version of Windows or any Apple OS and getting serious regressions or overtly user-hostile new "features" that you can't turn off.
I do think there's room for a modern desktop OS that doesn't have all the historical baggage of Linux. Not having a permissions model that sandboxes apps and the data they work with by default seems very outdated in 2022 for example. The traditional filesystem hierarchy is unnecessarily complicated and not well suited to modern systems. We rely on container technologies for professional work now because the package management and installation/update mechanics are so fragile (though no worse than Windows or macOS IMHO). I just wish the barriers to entry weren't so high now that it is tough for anyone to build a new desktop OS from the ground up any more.
