What kind of beginning you mean? If you start to learn linux than use Arch or Archman specifically. If you just want to use Linux as desktop go other alternatives.
According to my experiences; its good for trying kde but just that. I prefer openSUSE tumbleweed over it. Or just Debian Testing with KDE Plasma. (Maybe stable, version 12 is really updated for know.)
