There are frequent updates to the guest OSes (Fedora, Debian) and occassional updates to dom0, but they go faster than Windows or macOS updates. This is even true when Qubes updated go through Tor. They also don't interrupt anything nor force a reboot, which is a stark contrast to Windows and macOS.

I don't use night shift, but it should be an option in dom0 since that is running X11. I'll look for it when I'm back up and running.

No secure boot out of the box is a fair point, but they do have two more secure alternatives (Anti Evil Maid or Heads) which has the advantage of limiting the trust you have to put the BIOS.

I like Tails too. That's my go to solution when I need to use someone else's computer. I can just reboot before and after I do something risky, like downloading and running software vs something more sensitive such as encrypted messaging, moving money around, or signing into certain accounts.

I don't tend to do much of those sensitive things while on the go, let alone using someone else's computer, so it's not very many reboots to switch context in practice.

At home it's nice to have different nyms separated, easy backups, and different networking setups for different things (force everything through various VPNs, Tor, a combination of those two, or no networking). Those are the main three things I like about Qubes (beyond the isolation that prevents one vulnerability from meaning "game over", of course).
