Thanks a lot, Bugsy! 
Now... looks like we'll have Abe in all but start #2.
#1: Not bad, good production possibilities, but I personally don't like Floodplains as disease might strike until we get Hospitals... which will happen very late, if ever.
#2: Great start with a food bonus and good production capacity.
#3: Lots of grassland and plains... not so good on production, propably.
#4: Good start position, food and production nicely, but also has floodplains, which are a risk.
I'd personally go with #2, if not then #4.
