Hello bonbonboi,
I would recommend you to try the KDE- or GnomeISO from paintitblack folder, if your device more or less up to date. These are the most common Graphical User Interfaces under Linux and are both easy to understand.
If your machine is older you should perhaps try LXQT or XFce which need less resources, but you'll find your way through the menus and programs, too.
Nox is used for servers or stuff like that. And Xorg is somewhat for people who like it minimalistic.
Hope that helps, Timo
