The Most Polished Linux Distro
Deepin Linux (a Chinese distro) is in our opinion the most easy to use, polished and handsome linux out there.
There are a handful of "user friendly" linuxes distros out there. Elementary one of the easy going linux distros, but Deepin definitely takes the crown.
The UI is simply beautiful, elegant, user-friendly and reliable, flawless in our opinion. The distro itself is based on Debian-based, so you have a fairly large amount of stable and cutting edge packages available.
Deepin has a number of home-grown applications, like Deepin Software Centre, DMusic and DPlayer. It has its own desktop environment called DDE or Deepin Desktop Environment which is based on the Qt 5 toolkit.
Usually everything works out of the box, very little configuration or tweaking is necessary.
Here is a complete set of screenshots, from the install process up to the DDE Desktop.
