The biggest difference is that the spine on this robot is not articulated. Most of a cheetah's power for running comes from the strength and flexibility of the muscles along its spine.
It's just hard to beat the density and flexibility of a living mammal with a bunch of servos, chips, and batteries. We probably never will.
I'm not talking about power here. I'm talking about flexibility though. I think it won't be a stretch to think the hind legs range of motion could be extended by 10-15 degrees so the hind legs could hit a point further along the way.
