I put my bet on Striker, due to his surperior armaments and superior closeup and long distance weaponry along with vastly surperior armor. CT's thounder cloud formation seemed like a more defensive manouver than a a finishing attack. However location plays a large part in deciding the outcome. In a cramped city Striker is shown to be extremlely effective against mutavore. Although open ground would give CT a slight advantage i do not think it would be enough to stop Striker from overpowering CT with its surperior speed and sting blades. In real fights the main target is the head. CT's head seems extremlely exposed so it is possible Striker could end the fight in one punch to the neck. Also have to back Striker because it is Aussie and it would more than likely beat any other Jaeger 1 on 1 with the Hansons.
