When you get the Carthaginian reform, when do you for Native Administration and when for Punic Administration? And why?
You build Punic adminstration so you could get Punic Kleruchy
Native administration is when the only thing you care are recruitment and public order without having to waste much turns. In addition Native administration cannot be upgraded so you need to demolish it if you want Punic Kleruchy.
Punic District -> Punic Klereuchy gives fewer, but far better troops. You get 1 unit of Libyan Spearmen, always nice, and a unique recruitment system of settlers. In Africa and Sardinian Islands, you get 1 Scutarii Sword, 2 Scutarii Spear, 1 Balearic Slinger, and 1 Scutarii Cavalry, while in Iberia, you get Blastophoenicians. But in the end, it's all up to you. You want cool regionals, and don't care about buildings, go for Native Administration. You want sturdy but boring troops and better construction options, go for Klereuchy
