It really depends on the situation, doesn't it? If a nation is in desperate need of gold to fund an early expansion and to put up fortresses fast, Order would be a better choice in the short-run. If your nation doesn't need gold for expansion or doesn't have a need to build fortresses (*cough* MA Oceania *cough*), growth is more beneficial in the long run.
That being said, O3/G3 would give you the best result overall. But, you're going to have to look for the design points, after all.
