Personally, I'm going to agree with most people out there and say Sparta. Although you could argue Spartan society was controlled and limited to a point that is ludicrous (no commercial class was allowed to appear in "classical" Sparta and I am referring to "classical" Sparta and Athens in this post obviously). All Spartan men that completed the agoge (Spartan warrior training) were full time warriors and were the only Spartans considered to be Spartan citizens. Wealth was practically non existent in Sparta, when the rest of Greece used currency by 600 B.C. Sparta banned it's use. Yes, Spartan society in many ways was conservative, controlling, and limited to the point of being extreme. But in my opinion, it was also interesting and worthy of envy. Spartan armys were oftentimes outnumbered (such as at the Battle of Thermopylae a.k.a. "300" although that movie isn't extremely historically accurate) but still usually won or inflicted massive damage upon hostile armies. It seems to us now in this day and age that duty and honor were the only virtues taught and valued in Sparta, and this fact both propelled Sparta to greatness and crippled it. The concept of Spartan superiority above all other Hellenes (Greeks) along with the Athenians basically believing the same thing perhaps was the greatest factor in classical Greece never becoming one unified state. Imagine all of the accomplishments of classical Greece, now imagine if Athens, Sparta, Thebes, Corinth, and the other 150 or so Greek city-states could have been one joint nation, the possibilities are incredible
