I installed it on my endeavour laptop last night and apart from reconfiguring my dock-like panel and weather widget, it's all been plain sailing so far. Now I just need Tumbleweed to release it so I can update my main desktop!
My Endeavour laptop got it today. Couple of tweaks and it was running perfectly.
Funny you mention desktop: I've been waiting for Plasma 6 before rebuilding my Ubuntu desktop with Endeavour. Didn't want to jump the gun, find out that it impacts gaming performance, and then have to rebuild back again. :) Guess I have a desktop to rebuild now...
I reinstalled EndeavourOS on my main desktop yesterday, fresh install, just for Plasma 6. So far, big worth it even though I have a lot to set up still.
