Common Law, Civil Law or Shariah Law? Or an alternative system?

[So rightwing that I broke the Political Compass!]

These are the three dominant judicial systems of the modern world. Which do you prefer? Or do you find an alternative judicial system preferable?

Personally I'm leaning towards civil law for two reasons:
1)Some states(Egypt and Iraq) have abandoned common law for civil law, whereas no countries have abandoned civil law for common law.
2)Non-Western countries that escaped European colonialism(Japan, China, Korea and Thailand) all chose to adopt civil law rather then common law(despite Britain+America having been the most prominent Westerners to these countries). The exception being those Islamic countries which sustained Sharia law.

[So rightwing that I broke the Political Compass!]

Are Egypt and Iraq models to follow? And might not this move have to do with anti-British sentiment following liberalization rather than anything else?

Then why didn't countries that escaped French/Portuguese/Dutch control abandon common law out of anti-French/Portuguese/Dutch sentiment?
