What is the survival rate of a human figting against a T800/T850, a Yautja warrior and a Xenomorph?
I'm going to take my guess and say the Xenomorph would not last long in any batter given how it's viewed as an unintelligent foe focussing on its acid spit and agility. A xenomorph on the other hand has advanced alien technology with a very high IQ surpassing that of a human, while a T800/T850 is a computerized hydraulic machine tasked with infiltration and assasination.
I am a Yautja fan myself.
