KDE is now my favorite desktop

I have a terribly uninformed question. Ive been using i3wm ever since I learned it exists. Ive always had old machines and used to run Lubuntu, and at some point moved to i3wm. Its super fast and light which is what I care about the most.

I dont feel like Im missing anything, but then again a lot of people dont know theyre missing things which they cant imagine (before cars if youd ask people what they wanted, they wouldve said faster horses, etc etc).

So: What am I missing by using i3wm instead of for example Gnome or KDE? I dont care about pretty and shiny and animations. What else? Surely the whole holabalooba cant all be about pretty drawings and animations...?

(Sure, I probably would be able to find out by myself by trying these things but... since my starting point is the belief that Im not missing something, why would I be looking at these things...?

KDE and gnome have nice point and click interfaces that are pretty natural.

If you feel at home in a terminal then you aren't missing much. However, if you want a nice GUI to configure your bluetooth headphones or network without having to know the various bluez commands then kde is nice to use.
