You and the previous poster are talking about different things.

Gnome has consistent UI. Every app looks the same.

KDE has consistent UX. Every app works the same.

If users can learn a paradigm once and apply it everywhere, your paradigm can be more complicated as the payoff is also larger.

But if every app is different, users won't spend any amount of time to learn how it works. Every possible option needs to be obvious immediately.
