I’ve had very good experiences with both but wanted to give debian a try, after accepting that it’s nvidia drivers and Optimus support suck, I need to decide whether to use EndeavourOS or OpenSUSE Tumbleweed, not using base arch because I don’t want to go through the install hassle.
Just wanted to pitch in my experience and say my volume up/down keys on my keyboard worked out of the box, so it’s not a universal issue, and still worth giving OpenSUSE a try.
I do use NVidia with OpenSUSE, but I don’t use Optimus, so I can’t be of much help.
