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.
