Do you even play DM Dominator?
Ports might look amazing to you as they've got 4 TC's but have you got that enough food to spam vills plus Army as Ports which are a food heavy Civ tbh. Only if you use goons en mass and canons will mean that you might have some more food than gold.
Do you want to lose a battle that will cause you the game or would you rather win it and win the game? Look at games, only if they keep on running for a long time will you need those 4TC's (6 with card). Also there are much better cards to be choosen before 2 Explorer dude and +2 TC.
If you want to risk losing by going full vills as soon as possible then go Britts and there you have 30 vills after you've built all your houses, Minutes later you have reached the maximum with the "Estates" card. But truth speaking that isn't practical in a tense-full game.
Even Russia comes close to Ports in terms of vills, actually they could easily challenge them eco basis. You get 10% off every villager and I believe it takes much less time for those 3 vills to come out of a Russian TC than three from a Port TC.
Now we move on to Prussia, they have Vills like most civs coming out of their TC's but they also have the advantage of very unique, strong and versitile Wagons. These settler wagons costs 2 pop But are more than worth the 100 food and 100 wood as they collect more than twice the amount faster than the oridinary European Settler.
Spain, well with Spain settlers are as simple as they get. No unique settlers, same training time as all basic european settlers and a medicine card that will train them 15% faster, which is also a card for most European civs.
Now we move onto the French, this civ have the wonder of getting Courer De Bois which 80 of them are equal to 101 Settlers If I recall Correctly. Only the French gets this type of unit, unless that is you've coincidently chose a map with Cree's as Natives for example Yukon where you get to train 5 Cree CDB.
Dutch have one of the best if not THE best early game eco. They only recieve 50 Settlers, and yes these are the normal European settlers and they also cost gold which Dutch are heavy users of. But for the reason I say these have one of the best early game eco is because they have the ability to build banks which costs 350 food and 350 wood. These gives you a trickle of gold such as a factory would but on a somewhat smaller scale. ( I believe 2 Factories = 3/4 Banks)
And not forgetting The Ottomans which recieve free settlers automatically from your Town Center, I recommend you always Build 3 TC with Ottomans no matter what, 1200 Wood is not much when you think about what you get reconziled by the time its gg also wood is very ready unless you go intensive with your natives.
There you go I've briefly written about all the European Settlers, I hope that what I was supposed to write about either way It will atleast help some noobs when they want some information about villagers.
