So I pulled the trigger on USB3DDOCKFT (the one with dual laptop connections) and everything seems to be working mostly fine! The Fedora install seems to be a bit more stable than the Arch one.
The only issues I have are some traces of the mouse cursor, the sound seems to lose some bass through the dock, and when I switch back to my home laptop (arch install) the image on my large external monitor shrinks. If I mess with the Gnome display settings it fixes it, so the fastest way is to open my laptop and close it again.
The other problem I have is that I don't have redshift
thought this would be a dealbraker, but I've manually removed some blue light from the monitors and I have a filter on my glasses so it's been bearable.
