In the past I've tried to use KDE and just never found it all that appealing. Sure, it was pretty, but it was also pretty buggy in my own experience.
Last night, for no particular reason, I decided to install KDE Plasma desktop environment on my laptop to try it out again and I've got to say... it's not bad.
Now, I'm an XFCE man through and through. Aside from some very short stints with Cinnamon (w/ Mint), XFCE has more or less been my choice for well over a decade now.
With that said, I'm not switching to KDE full-time, at least not anytime soon. But I was pretty impressed with it after having not even considered it an option for many years. May be worth checking out again: https://kde.org/plasma-desktop/
I'm considering tossing it on my workstation as well to see how it does in multiple monitors and under real use.

I used XFCE from 2006 until around 2011 and it was pretty nice and lightweight. Then I switched to a laptop running Gnome for a few years, but noticed later versions became a bit sluggish. On my current machine (a laptop based on Ryzen 7 with 40 GB of RAM) I switched to KDE Plasma because its performance is pretty good, it's compatible with Wayland and it has a lot of built-in applets and stuff. And it didn't have the frequent CPU activity spikes I was seeing with Gnome.
Despite the lack of Wayland support, XFCE is really nice, although I'd consider LXDE or Enlightenment on a low RAM machine. Enlightenment looked amazing last time I tried it on an old laptop.
