Best Infantry Unit In Game?

[Grriffon]

So for grins and giggles, what does everyone think is the best infantry unit in the game, This can be any infantry, recruitable or mercenary.

For myself, I'd have to go with either the "Mercenary Thanes" that can get the gold sword upgrades, or else the Elite Seleukid Spearmen with like 38 armor, whose name I can't remember.
