I absolutely love Gnome, but only when I have a touchpad/touchscreen. It blows KDE out of the water in that regard. However, it loses its shine for me when transitioning to a traditional KB+M, and KDE takes the cake there.
Basically, KDE for my main desktop, Gnome for my laptops, tablets, etc.
I think the defining feature for me on Gnome is the workspaces. It’s just so fluid in a way i personally haven’t found KDE. Not saying KDE is trash on touch or anything, I just prefer Gnomes feel.
