I assume your '>' means better?
Can you share a bit of your reasoning for this very particular ranking, or is it simply based on personal experience?
It guarantees an early pirate and thus an early start to the more interesting negotiations. The views based on experience.
Why is 3 player so much worse?
Not enough factors, weak negotiable positions and too easy for to Governor to become self-sufficient.
What are the main intents of the other two suggestions?
It makes the treasure shipping & thus the pirates more interesting and smooths and nerfs (a nice combo) what can otherwise be an easy victory path (treasure).
