Ok
A Tyi would win anyday-Metal insides and organs

They would have some sort of weapon built into their bodies that would let even an unarmed pilot be a threat. The metal insides would stand up to the superhuman speed of their organically modified enemies. If two pilots squared off-not the military brutes or marines that would be built for the purpose of super human ground fighting. The pilots would be built to have super human reflexes and speed of thought but their bodies would probably be alot less hardened for actual combat without their ships. Which would win in your mind....
