Did a bit of basic testing
If we settle on the Stone (and find nothing exciting in the initial city radius)
T5 warrior
T10 warrior & Pop 2
T14 found Hinduism
T19 worker finishes (2 turns on a mine, then start on farming corn T21
If we settle 1E
T8 stop warrior at 8 hammers and start worker at Pop 2
T12 found Hinduism
T20 worker finishes and can start farming the corn T20, resume warrior having lost 1 hammer to decay
It seems that settling on the marble or stone is significantly better based on what we know now.
Advantages of settling on stone/marble
lots of scouting (3 warriors wandering about)
Continues to produce +2 hammers more than not settling on stone or marble for quite some time
Disadvantages
Slower founding of Hinduism (which I doubt is a problem and if it is we have lots of spare time for the next 4 months
)
Start improving the corn 1 turn slower
less overall research (~25?)
The extra scouting possible with warriors built with the hammers from settling on stone/marble (and possible worker stealing) is very valuable I think. This is worth more than any slight advantage settling 1E might have long term in hammer production.
I'm finding it hard to imagine what our warrior might find that would encourage us not to settle on stone or marble.
