My CachyOS / KDE install with pure Wayland has been buttery smooth and recently got an update that finally lets me calibrate the max brightness of my HDR OLED monitor (which was the monitor's fault. Not even Windows could make it work properly for non-games until now). CachyOS is also the first distro I've used in years that does things close enough to way I like out of the box that I haven't bothered to update my system reinstall script in months.

I've also been giving Bazzite to some non-tech people who have not once asked for help. That one is immutable and Wayland only, so it's a further testament to how far Wayland has come if you're on an up-to-date-enough system.

Sadly, I'm stuck on older Ubuntu for my work laptop because the mandated security software won't run on anything better.

What is the mandated security software? I’m asking to avoid it in my own org.

I've had to patch the .desktop file in debian for killbots to make it start via x11 because the wayland one was unplayable.
