I installed Linux mint on a trusty old thinkpad. Used it probably 5 times over the course of a year. Then installed arch on a newer T480s I received from work. I am a complete novice. It is literally that easy. You download the arch installer, follow the wiki on the 2 or 3 commands needed for internet, then type archinstall. Thats it. You literally dont even have to install anything else, especially if you choose desktop instead of minimal like I did. I have no idea what anyone is talking about it being difficult. Its easy.
