1. USB 3.0 KVM switch can't connect a monitor as no video port like VGA, HDMI, DP ports available. Two computers require 2 monitors, while USB VGA KVM or USB HDMI KVM only requires 1 monitor, you can switch by pressing button between 2 PC's.
2. USB 3.0 KVM can't send video or audio on monitor or TV, and VGA can send video at 1080p resolution, while HDMI KVM switch can even send 4K video & audio on monitor or HD TV.
Overall, the USB VGA KVM switch provides all features that usb3.0 does. But if you want to send 4K video & audion on HD TV, the HDMI switch is the best option, like asin B08DR2SHCP.
