We already do have two standards, Comp vs Comp games wont/can't necessarily tell
you anything about which program is best against (the majority of) humans.

 One chess program being the best playing other chess programs and one chess
program

versus computers to figure that out, but currently the (published) human vs comp
games are limited in number.

Is it better marketing to show you can destroy all

It depends on what people pay the most attention too  compvs comp games or comp
