I switched from Manjaro to EndeavourOS and can confirm your experience. A lot of updates on Manjaro broke something on my system. With EndeavourOS it is different. Yes, it is really solid and makes a lot of fun for gaming. Do you have any recommended Tweaks, like you said?

I recently ordered a Brother printer, and it just works. “Brother MFCL3730CDNRF1” At one point it was a bit tricky to add it to Cups, but after it, it worked flawless.

I use an AKG K702 with Easy Effects.
