pacman and aur with preconfigured DE, it saves a lot of time. I switched to Manjaro after I got tired of tweaking arch even for most trivial things every single reinstall. Its the best distro for learning though. Apt or rpm distros can barely compete with the amount of available and up-to-date packages in aur.
Some people say that Manjaro is bloated, and I understand. But if you want a customized setup I find it easier to install Manjaro, remove what I don't want and them customize than installing doing the opposite with Arch
