A picture of Lara Croft in new Tomb Raider hand in hand with Lara Croft from the old Tomb raider Series. The new one labeled GNOME and the old one KDE.
I feel like this is used either by someone who hasn't used KDE in a decade or has been using Linux (Ubuntu) for less than a year.
The worst thing you can say about KDE is that the default configuration is pretty basic. However, that's arguably a good thing because that format is straight up better for productivity.
KDE has also embraced user choice. Not only do they design the desktop and applications to be much more configurable than GNOME. A power user can customize KDE in a way that seems to personally offend GNOME developers. In addition, KDE 5 designed their libraries in a way that other DEs can leverage them while still doing their own thing. I haven't kept up, but at one point that was a huge boon to LxQT development.
Above all else, the KDE team seems a lot more reasonable than the GNOME team. Over the past decade, KDE has worked hard to rebuild trust after their disastrous 4.0 rollout. Meanwhile in that same period four different groups of developers have decided to go their own way because they felt the GNOME team was impossible to work with.
