Endeavor is fine. But when it came to performance I had a number of issues. By default it put my i7 into power save. One could use core control to put it back into on demand or something more reasonable after every boot. Or go in and change the configs manually which I did. But that's still beyond people in general. Also for whatever reason if I had more than one app actively using the GPU. Say blender open using GPU, accelerated cycles etc. And another window open doing something with OpenGL and Vulcan. I would get the whole system hanging under x11. I'd have to drop to the terminal. And kill all of it off and restart it again. And not just isolated. It was heavily repeatable.

I ended up giving Garuda a try. CPU scheduler is much more same out of the box. Graphics card support under x11 and Wayland has been rock solid as well.

They're both arch. And it is all personal anecdotes on isolated systems. So make of it what you will. I like both systems though and actually have computers running both
