Has someone compared Growth with Order already?

The main point is that Growth based income bonus grows exponentially while Order stays the same.
So with CBM and assuming that the province has the scales all the time a province with Growth 3 should break even with a province with Order 3 on about turn 18.
100.6% ^ 18 * 109% = 121% (vs 121% gold income from O3)
On turn 37 the province should have generated more gold over the whole game than an order 3 province. That's hardly the point where gold gets useless or someone drops several Armageddons (and after that O3 is useless as well).

Also if you spread your dom into provinces you can't take already (knights, elephants) growth benefits you but order won't.

So I'd say if you want to take luck and need money G3Lx isn't a bad choice instead of OxLx.
