This debate will go on forever. If you are unsure, nothing stops you from either trying both, or installing both or live booting to test.
I find KDE completely smokes Gnome across the board ever since Plasma 5. It uses less memory and works extremely well. The layout is same as a person is used to from Windows and MacOS. If you don’t want to configure something, simply ignore it.
Either will always have the occasional bug or screw up, because it is simply the nature of things.
