So, does this mean the Terrace Farm wins?
Lets give it a crack.
Chateau- 19
Feitoria-13
Kasbah-9- I play with disable start bias on. Rather pointless if not on desert.
Polder-17
Terrace Farm- 25
Too bad about the Woodcamp. Those tiles do turn into monsters with a little work. Much better than Kasbah which turns a terrible tile into an "ok" tile. Chateau really is a nice UI that blends well with France, but I'll look at these as if a city state could gift them to me, which would I want. Lets get to the final showdown.
Up - Polder. There is no trade-off. You get a tile that you would otherwise put a farm on, and you put a super farm on it. On flood plains thats 5 food, 1 hammer, 2 gold. For a marsh you're getting 4 food, 2 hammers, 2 gold. So from a tile yield perspective, there is no contest. None.
Down - Lets take on the Terrace Farm. Whats it do ? It lets you build a farm on a hill. Thats it. Get a hill next to a river and you've got the Inca UI. If the hills next to a mountain you can get food yields equivalent to a polder.
So why's this even a discussion ? Scarcity. I agree that you're more likely to get a no use roll with the Dutch, whereas a "bad" Inca roll just means you can farm your hills. In the Polders case its not usable, in the Incas case its "meh". Win for the Terrace farm.
Good to great rolls favor the Polders. You want super cities, you want a good to great Polder roll, not an Inca roll. So if you're playing for greatness, roll with the polders.
