A few things: 1/ the system doesn’t need to be connected to a network, or can be on a private/secured network. 2/ You can make changes to BIOS and other elements of the system that the OS can’t “see”. 3/ If the system is sleeping or shutdown, JetKVM can send a wake-on-LAN signal/magic packet.

I’d say for many use cases, it’s not better than RDP/VNC, but if you’re looking access that is independent of the network and state of the system, JetKVM can’t be beat.
