While I admit most of my arch reinstalls are mostly the same,I feel that archinstall script is genuinely good now with most defaults I need. The rest I can just add it in the installer extra packages or chroot post install (which is offered as a choice at the end).
I just could never bring myself to use distros that are technically the same distro with calamares slapped in top and whatnot. I mean ‘pacman -S {packages}’ is straightforward enough for me.
