Another option is the Aten CS1944DP - 4 input dual 4K60 USB3 KVM switch - I have it and it's rather wonderful given I now have my work laptop here due to covid - not cheap, but it's really, really good.
Not cheap is quite the understatement. I could easily just get another screen for less money.
Depends on your use-case - I already have two screens but I need them switching between multiple computers - there are very few options for dual display multiple input KVMs which can support 4K60 and USB3
Both of the KVMs meeting his criteria on that page are sold out (and one is a pre-order as well as being sold out).
