Yeah, I've been on Plasma 6 with my Manjaro Unstable desktop. Not a terrible experience and I've yet to encounter an AUR package giving me problems, aside from outdated ones. Honestly, I've given Endeavour OS a try on my laptop and will be switching it back to Manjaro when I find the time. It's a fine distro, but it feels like it tries to give you an excuse to "bust out the terminal" once in a while... Which isn't my thing anymore.
