Templar Knighs vs Persian Immortals

I'm taking the Templar Knights from Kingdom of Heaven vs the Persian Immortals from 300. 1000 Templars vs 1000 Immortals. Battle site is northern Assyria (not Syria). Who wins? The elite knights or the badass infantry of Ancient Persia.

300 was fully stylized and overdone; considering the Spartans who were portrayed to be somewhat super-human were killed by the Immortals, the Knights who were basically just Knights would get their assholes kicked in.

Templars Rock the Persians. No question about it here.

Kingdom of Heaven sucked.

But the Templar Knights of old were hardcore.
