The default UX used in Ubuntu may actually be confusing for newbies, as it’s quite different compared to Windows.
It's not that different, dude, and it's not like they don't give you a tutorial on first boot either.
Perhaps a distro which uses KDE, XFCE, Cinnamon, MATE or LXQt by default.
Gauge your audience dude. A Linux newbie will not know wtf anything you just named is. (For any other newbies reading, these are all 'desktop environments' - essentially collections of programs that make up a user interface)
