It's not hard to set up if you already have sufficient baseline technical knowledge to feel comfortable copy-pasting the right commands from the Internet with hope that you don't brick your computer (which ironically fedora or opensuse kinda did although I eventually found out how to work around the failure which makes my laptop permanently unable to use an older version of Linux lololol).

Arch was really easy to set up, I followed tutorials for fedora from fedora which never worked, and opensuse worked until a power outage then never again. So easy. So simple.

Secureboot with shim is the easiest, the arch (/standalone) way seems to work better and more securely since it's my own keys, but again depends on feeling a lot of unearned confidence. Some distros like Ubuntu and suse include mechanisms for secureboot, others do not, hence hit or miss.

Tldr I know what you're telling me, and from my pov and experience none of that changes what I said for the average "go on, try Linux, you'll like it" user.
