the main differences!!

I installed a Fedora KDE Plasma spin and it enabled features on my laptop i didn't know existed. It was nice. Windows 11 sucks. I'm happy to get rid of it.

Kinda depends: for me pretty much all de-s are complicated. I mean what happens when you want a de to do X? I used to go to settings/whatever, then google the problem in like 10 different ways when I inevitably don't find it. And with wm-s you just search the wiki

I thought kde users were windows users who are afraid of change.

I once installed Kubuntu on my laptop and when I booted it, it was very overwhelming to see so many options, I realized it would take me two or more days, and it feels extreme, and you also need the terminal a lot. That's why I love Ubuntu GNOME, but it's ok if you like KDE Plasma.
