What is the best Phalanx unit?

[Tellos Athenaios]

Pantodapoi are excellent supportive phalanxes: their AP axes come in handy. And being cheap is a good thing when the main job you use them for is to survive the autocalc against lots of missile infantry the Eleutheroi come up with... At least for me the Autocalc is a lot more easy on my armies if I stick a phalanx unit or two in my armies.

EDIT: Also with phalanxes it is about having the right formation depth. For example if you are up to superior phalanxes but do have the greater number it pays to double your formation depth: the phalanx will literally hold twice as long, and it'll push twice as hard too.
