What makes for an amazing cable? For USB, if it carries data and power, I’m usually pretty happy with it.

For USB, if it can carry 65W+ of power to my laptop as well as the Keyboard/Mouse inputs, 4K/60Hz display and audio back to the monitor as well as KB/Mouse and perhaps some external storage or network adapter, that's a pretty amazing cable.

I also have preferences between my cables by the quality and aesthetic, I prefer some over others because they look or feel nicer even if in testing they contain the same conductors, but that's just ... me.

I currently have 3 such cables connected to my work laptop each sending 4K/60Hz video to each of my 3 x 4k monitors, audio to my soundbar and one of them is powering the laptop at 90W and sending my keyboard, mouse and webcam inputs back.
