The Persian empire was an extraordinary example of efficient government over a huge area, with a skilled bureaucracy, a common currency and moderate taxation.
Persian kings tolerated cultural diversity, were not religious fanatics, and earned the deep gratitude of the Jews for allowing them to return to their homeland. Cartledge keeps up some of the old stereotypes (the Persian forces are 'hordes', and Greek rulers in Asia Minor who accepted Persian rule are 'quislings'); but this just makes it harder to explain why most cities and statelets in mainland Greece were willing to welcome, or at least accept, the Persian invaders.
As for Sparta, this prototype of Western values turns out, in many ways, to resemble the sort of
society known to us only from visits to jungles by anthropologists. Infanticide was the rule for inadequate male children; the lucky survivors spent their teens in boarding schools where, as part of the training system, they were assigned older men as lovers; all male citizens were trained only to be warriors; their wives greeted the news of their death in battle with delight; and only the battle-dead qualified for gravestones. Cartledge himself argues that Leonidas and his Three Hundred were a 'suicide squad'; casting around for parallels, he does consider the suicide bombers of today's Middle East, but then plumps for the Japanese kamikaze fighters instead. Not quite the beau idéal, then, of a J. S. Mill-style view of Western civilisation
