The reason I feel a Spartan has a big advantage is the armor.you take a titan guardian,put him in high tech armor enhancing his strength and rechargeable armor,you get a spartan.the guardians have to charge their ability before using it,and I am pretty sure master chef would kill them before that even happens.then if they do survive long enough to charge it,the Spartan armor would take the blunt of the force anyway...Master chief wins this battle hands down.interesting tho that the title for the next installment is titled Halo 5:Guardians.
