Arch Linux

Figuring out what you actually want or need is part of the distrohopping journey. Most people should start with Ubuntu, Mint, Debian, Frdora or something like that.

Starting with Arch is difficult to recommend unless you know the person really well. If you know they might be the kind of person who tends to require very specific things and is willing to put the time and effort into getting exactly that, then Arch might be the right starting point. Otherwise, starting with a more main stream distro would be a better option.
