Popular opinion seems to be that #GNOME and #KDE are "fighting/competing."
Sure we have our differences in philosophies and design, but it's way more akin to siblings having small spats. But in the end we are siblings in #FOSS family and I like GNOME folks a lot. And if anyone attacks my siblings, I'm there to defend them.
We can and we should work together as much as possible, not just GNOME or KDE but all other DE's too like #Budgie and #XFCE to be the best computing experience possible.
It's not perfect and it's never gonna be because perfection is unattainable, but perfect is also enemy of good.
