B787E
You have been supplied a lot of irrelevant and confusing data.
As Intruder said, what matters is how much fuel is used to carry a certain payload over a certain distance.
Normally the smallest plane which can fit in the target payload will win. Forget the 787 if you have 100 pax.
"Fuel Efficiency" is a notion dear to marketeers but not something which is easily measured in the industry.
