I don't use arch, that's the saying. I used mx linux and have Antergos as my other backup OS. I don't like to have to jump through hoops for an installation and would only install Arch as a learning experience. As I've seen from video's I have no chance of installing Arch at this time without notes or another computer with instructions on it. As for Gentoo, not worth the effort for me even if I had notes or another computer I would consider it more work than fun and I would have to install a bunch of stuff after. Besides I find compiling stuff a pain in the ass when I can just install precombiled binaries with other distro's with ease.
