Am I the only one who likes KDE and Plasma Desktop?
Not even close. It's always my go to and despite the ancient hardware in my sig I never have any slowdowns or other issues with it. Running it on Manjaro and haven't had any problems.
I said it before and I'll say it again, I was quite surprised and taken with Manjaro. For whatever reason I have never liked Debian and Debian based distros. I can't tell you what it is about them I don't like but it's always something no matter how many I've tried and with many different DEs. I simply don't like them. openSUSE was actually my main go to for my use and I still run openSUSE Leap on my server but definitely love Manjaro on my main system. Despite not having any issues with Manjaro I don't foresee myself ever running that as my server OS and plan to stick with openSUSE in the future yet.
