I daily drive FreeBSD with IceWM, four screens 2@4k, 2@1080p running with Xorg on a Sapphire 5600XT, I can't fault any issues.

Exactly. When it works it is great.

I stick with a single 43" 4K@60 but it was a bit of a challenge to get on the happy path:

All systems can have issues. But the more widely used systems are at an advantage.

Are the screens directly connected or do you use a docking station? If docking station, does it require DisplayLink drivers to drive the monitors?

No docking station.

Although the 2x4k monitors are daisy chained. I was surprised when it worked first time.
