You mean xfce? KDE is bloated. Yes it’s still bloated even if Valgrind says it has no memory leaks.
[edit]: I forgot to mention as well, at least on arch you dont have to install the (I forget the package name exactly) kde applications package off pacman, if you don't install it you'll need to install dolphin and a few other things but it really cuts down the bloat.
But some of my Clients use windows and were just "forced" to upgrade their hardware and use Windows 11.
