I think the parent comment's choice of "minimal work" was key. In my experience, KDE requires quite a bit of work to set up because it encourages you to adapt the system for your workflow. GNOME, on the other hand, encourages you to adapt your workflow to the system, which is minimal out-of-the-box, and IMO doesn't take much effort or work to do so.

Regardless, I think once KDE is set up to one's workflow properly, it stays out of the way and can remain out of the way on new systems by transferring the config files. It just may take a lot of upfront work to get to that point and you can get easily distracted tweaking the minutiae over time. For that particular reason, I also prefer just using vanilla GNOME (with only the AppIndicator extension for DropBox and Steam tray icons). Granted, that's a "me problem" because I get easily distracted and can never stick with a specific setup when there's so many options available for me to tweak.

TL;DR: Both KDE and GNOME can be minimal, but the latter requires "minimal work" because it's minimal out-of-the-box and there's not much work that can be done.
