I will see what I can do tomorrow. From what I ca see, the phalangites are the same. My hoplites, peltasts and archers are different. The site doesn't have pictures of the Companion cavalry, but from the few pictures I can find on the internet mine are different.
It is almost like there are two styles, the infantry are quite nicely sculpted. The cavalrymen look a bit squat and squashed.
I had some lovely Spartans as part of a hoplite army - unfortunately I sold those and the newer Spartans don't look as good.
