I find it hilarious how much religion is put into Gnome vs. KDE in this case. I did use both. I honestly have no strong favourite. After that many years of Linux desktop environment DE hopping I came to the conslusion that the DE should get out of your way and allow you to focus on your work.
Both Gnome and KDE support that. Actually Gnome a tad better as it gives you less knobs to turn an waste your time. Accept the defaults and if defaults are bad move somewhere else.
I pick the software best for my uses and then look at which desktop supports that software and workflows around them the best. Not always clear/clean selections possible in my situation - I've a jumble of GUI designs and frameworks used, so I favour a more agnostic desktop.
