I’ve seen people suggest Ubuntu without mentioning Kubuntu, but it seems like most people (especially gamers?) prefer KDE Plasma. I’ve seen people complain about Ubuntu’s GUI and lack of customization, but then no one suggests them to try Kubuntu instead. It seems like people just don’t know that Kubuntu exists.
Also as an aside, people often criticize how slow updates are on Ubuntu/Kubuntu/etc, but if you enable the backports ppa then it’s actually pretty quick!
sudo add-apt-repository ppa:kubuntu-ppa/backports
I don’t have an Ubuntu machine at hand but I’m almost 100 % sure (because I used it in the past) that you can manage repositories via GUI and activate backports by simply activating a checkbox.
Very slightly less of a usability nightmare, especially for beginners who cannot be expected to know this stuff, especially when actually user friendly distributions take these troubles off the user’s hands.
