Time and again, someone (usually madscientist) preaches the great worth of ORG over FIN, but math>rhetoric.

Like I said, I am in the minority
But math only goes so far and you know it. We can talk ourselves silly with late game math, the civic upkeep at the end of the game not helping that much.
But this game is much more fluid and dynamic and cannot be tallied in a simple math equation. You have to look at the entire game as it's played out.
1)Cheap early lighthouses for food
2)Cheap classical courthouses at a time where expansion is usually stifled.
3)Ability to run expensive civics like OR, Bur, Fued, Slavery, Caste in mid-game at a time where markets/grocers/banks are real hard to build fast.
4)Ability to build fast courthouses in conquered lands to rebuild the economy.
5)Ability to industrialize faster with cheap factories.
6)Ability to stay out of SP and stay in FM for corps for large empires.
These add to your flexibility throughout the entire game. It helps not only in saved commerce for science or gald for the treasury, but gives you added options for production.
Financial offers a very big advantage that is limited to the slider. It is most powerful early on, but any financial Civ can be overcome by having more cities and you can do that with Organized.
Finally, I told the OP that there would be a slew of confusing and contradictory posts regarding FIN vs ORG
