I want to pull knowledge of unix systems
Gentoo with a custom kernel built on the principle to throw out everything that does not need to be added
And so, for the beginner, I would choose between Linux Mint + Cinnamon and Deepin + DDE
Fedora, Ubuntu, CentOS, openSUSE
Fedora - test polygon RedHat, but IMHO even more stable than Arch...
Ubuntu is a good choice to start with, posovetovali me Mint made on the basis of her
CentOS - took fedorino grief finished all the things g that RH is pushing for the grandmother... not yuzal on the desktop, for servers it will last on the ears...
openSUSE will be the best choice, if You, unlike me, a supporter of rpm/yum (I personally prefer the dpkg/apt, better yet, emerge nothing came up)
