I use KDE plasma because I’m new to Linux but also want something minimal system-wise. I love the programs and the interface. Maybe my opinion would be different if I spent more time with other DE’s or used it as my daily driver, but I’m sold on it now.
GNOME is definitely more user-friendly for someone who is moving over from Windows/Mac. I wouldn’t recommend KDE to someone who is just going to stick to using one-click apps.
