Any Arch-based distro because of the rolling release model, the excellent pacman package manager and the AUR.
Especially EndeavourOS. It's Arch Linux with a Calamares installer. Not that the Arch Linux setup process is hard, but it's a pain. I did it once and never again. EndeavourOS uses the Arch repos plus its own tiny repo with stuff like the Welcome screen, some themes and yay, so it's pretty much Arch with different branding.
