I can't get my head around why Gnome doesn't have an option in settings to prevent laptop going to sleep when lid is closed. In KDE you can configure that and much more regarding laptop behavior when charging vs on battery.
Why there is no option on Gnome to ungroup windows in dock/launcher without installing third-party extensions. On KDE it's one click. Not everybody likes to click 2-3 times to open desired window.
Gnome's default image viewer can't even crop or resize photos.
There is a ton things like this that make KDE far more usable out of the box than Gnome.
The only thing that is better on Gnome is HiDPI handling. KDE works kind of OK with wayland on HiDPI screens but some apps have issues with very slow scrolling, e.g. SublimeText and LibreOffice apps
