Linux

Nope, Arch is not noob friendly, you have been using Linux for long enough that you forgot how everything was different when you started. Also Arch hasn't changed much in 10 years (I should know, I have been using it for 15), if it wasn't noob friendly before, it's certainly less so now that it doesn't has an installer and the wiki makes you jump from one page to another instead of having all of the steps for installation in a single place.

I agree that Ubuntu is not ideal, which is why my recommendation is Mint. I also agree that Arch is not hard. But if you give a new user who just wants things to work Arch you're setting it up for disaster.

For users that are familiar enough with Linux that they feel comfortable on the terminal, yeah, Arch is a breeze to use, but you need to understand the difference between "power user friendly" (which is what Arch is, i.e. allows power users to have an easy time, by for example having a large user repository) vs "beginner friendly" (which is most definitely what Arch is not, i.e. give users an easy out of the box experience where they can figure things out without needing to read wiki pages). Most new users need a beginner friendly distro, and shoving Arch down their throats is not the way to do it.
