Forerunners have an edge in individual infantry,Orks have numbers. The Forerunners have trillions of Onyx sentenials. As for Seekers,a single 800 metre long ship carried a small army of the things, and in action they created explosions large enough to be visible from orbit. Also,Onyx Sentenials can fly,so Orks can't meelee them.
