Do you have a link? If it is the one i remember it was about keyboard-to-output responsiveness (and the winner was something like a C64 or Apple 2 or something like that), not overall UI (and i'm a bit skeptical about the dumb terminal part considering the communication latencies involved, especially in the 80s).
