I once installed the kde plasma desktop, but then again it requires more cpu usage. I guess the pc requirements for ZorinOS using a kde desktop will be much higher, meaning that the overall user will have to be informed of this before installing.
This isn't true. KDE has lesser memory footprint and resource usage than Gnome. Gnome is probably one of the heaviest DEs out there. KDE on the other hand has been optimized a lot and has comparable resource usage to XFCE.
KDE also supports a lot of things Gnome simply doesn't (Blur effects for example, Gnome would light your CPU on fire if it ever had Blur, KDE on the other hand does it gracefully) I don't think Zorin's relationship with Gnome is going to last long, especially when Gnome is restricting everything and will now not even allow themes in the future.
KDE feels like the obvious alternative for ZorinOS but I'm still not sure how that'll turn out since KDE can be extremely complicated and inconsistent at times.
Maybe if Zorin team manages to maintain the current Gnome version (or 40) it could work but Gnome's future is not very promising as the first choice for Zorin.
