What was the superiority of the Persian army over the Greek?

The Greeks had a proven tactic of using their warriors (hoplites). Therefore, the majority knew how they could and would act. At the same time, it was not always possible to oppose the hoplites with something due to their coherence and training.

The Persians possessed a wide variety of troops, including those from the conquered lands. They could significantly diversify their tactics, as well as expand the scope of application. They also had high-quality cavalry, siege and throwing weapons, and also had war elephants.
