Number 1 is pretty good yes, but the looks of it gives me suspicion on the surrounding terain. In my experience, more forest is a sign of more shields in the area, at the cost of food. The best part of number one is it's non shore appearence.
However, if the surrounding forest has some game, then it's probably as good as 2.
Number 2 is good. That river looks promising, and the land gives hint of fertile-ness. If the water seen is a fresh water lake, it's even better. If it's not fresh water, then it's the ocean, and rivers run into the ocean eventually, as we all know. That means the seen river is a longer river
3 is a waste initially. You'd have to chop down a good bit of jungle to even properly use the three cattle. However, the ultima output is good. The reason I oppose it is it is a coastal start. I don't like coastal starts.
The main reason 2 > 1 for me, is because I have bad experiences with too many shield instead of food bonuses.
