Just say “better.” Gnome and KDE are decidedly not perfect, but they are both quite usable even by casual windows-only non-techies.
FWIW I’ve been using Linux as my primary desktop OS for more than 20 years—it does no one any good to oversell it. Touchpad scrolling rate is still broken on Gnome/Firefox. Angels have to sing (or use xorg) to make s3 suspend work. Fedora auto-update can break if there’s “too many” packages to update. Touchpad scrolling can be misinterpreted as swipe-left or swipe-right by KDE on some hardware.
The point is, if you bang against any of these sorts of issues in Windows, you’re frequently stymied. On Linux, you can either fix it, or at least route around the damage with an alternative.
Most of these enterprise software (for non technical users) these days is just a web app so a vendor not releasing their software is not a problem here.
Like schools? ChromeOS is Linux and seems to be doing ok.
Outlook became popular because it was tied to Windows 20 years ago, but today this just isn't the case.
And besides, it's far easier to migrate between two webapps than it is away from a native app full of infra.
I have zero confidence in that testimonial, given my own experience with open source desktop environments, and KDE. zero confidence whatsoever.
The experience is so much better I really don't get this mentality.
* You often need to do non-standard system tweaks to get the system in a working state. It's everything-doesn't-work-by-default.
* You often need to install/prevent instalation of bad quality drivers and associated bundleware to make devices work.
* Microsoft can't decide what UI framework they will support (or drop support) so built-in applications happens to be built with the current "thing", the old ones staying on the older unsupported frameworks.
* You need to constantly tweak a combination of Windows 3.11 control applets, Windows 95 control panel applets, Windows 7 unified control panel glass, and Metro Settings Universal Windows Platform app to keep things working.
* Microsoft can't decide what random widgets go on the taskbar, or the file manager, or your start menu, so it's always disrupting things every few updates.
It is arriving at a point where the only "consistent" UI thing in Windows is Steam, and Steam isn't built-in, and is a hot mess of inconsistent UI itself.
