I like GNOME's workflow, more importantly it breaks less often than KDE does for me. My fiance's computer uses KDE because it has a more Windows-like UI, it's also the one that runs into weird graphical glitches and issues.

Examples, we plugged the new TV into it to watch something recently, since then the lock screen started glitching the fuck out having two different clocks flickering overtop of each other, even back on the original monitors.

New headphones didn't work right away because it had defaulted to an incompatible audio stream, changing it was buried under three different menus... we knew it wasn't the headphones because they worked fine with my computer, using GNOME. I've never had to dig through settings like that to use headphones with any other OS or desktop environment, but I did with KDE.

From the sheer amount of people that recommend KDE I have to assume that for most people it works, and that's great. My experience is that it's buggy and fiddly to use, GNOME for me is not. It's what I use on my main computer so that I don't have to troubleshoot stupid shit when I get off work. I like the less cluttered UI and the multi-desktop focused layout, plus it feels WAY more polished than KDE which has always felt jank to me.
