Factions with most developed unit roster

[Frtigern]

I'm enjoying the game but am wondering what faction has the most developed unit roster which specific to that faction and/or culture? I don't like fighting clone armies of my own. I want to show up with totally different units, but with the most variety. Is there any factions like this?

Lusotanan, Taksashila and Carthage are some factions with different units from there neighbors. From these 3 Carthage has the biggest number of troops.

Can the Lusotanan build the high roads and stone walls like their Arevaki neighbours?

Playing as Parthia leads to some fun asymmetric battles, as your cavalry archers and cataphracts try to deal with the Seleucid phalanxes. Of course, you do have to do some nomad-on-nomad fighting, too...
