I have a Iiyama with build in hub, at first it seemed ideal, just plug everything into the monitor. But my mouse glitches when used through the hub (MX Master 3S), the internet cable is only available to the active computer (so no tasks requiring internet can run on the other computer).
All in all, I just use the USB-C to HDMI switch functionality and couple the computers to keyboard/mouse via bluetooth, plus I bought a switch for the ethernet. It's a shame it's so suboptimal.
Another minor annoyance is that when I turn off one computer and want to switch to the other, the display turns off, taking about 5-10 sec to do so. Then I manually turn it back on and it's ready in another 3 sec. So I do this thing where I hover about the turn-off button, hit it and immediately switch so the monitor won't turn off.

It's hard to make convenient tech it seems.
