KDE feels like an unpolished Windows desktop to me. I find it difficult to do things the KDE way when everything feels like Windows on first glance, but doesn’t 1:1 behave like Windows. It’s a disjarring experience for me, and probably others who migrate from Windows to Linux. I also think that Gnome has better touchpad gesture support than KDE, which makes Gnome the logical choice for companies that sell Linux laptops.
