Lapdock (Screen + Keyboard only) alternatives

I am looking to get an alternative to the Nexdock as a sort of KVM that I can use to connect to multiple computers for maintenance as I have very limited space in my apartment. Previously I had a Nexdock that I bought 2nd hand, but it was awful, didn’t want to connect through USB-C for video or keyboard passthrough, which defeated this purpose to me.

Do you have any experience with any of these devices? Is there one that you would recommend in particular?
