A Lear 31 beats the 777 hands down, 96% lower fuel burn!
The -8F carries 308,000# of freight. The 777 carries 226,000#
The 777 carries 27.7% less freight and burns 25% less fuel...
Point is the -8F has the advantage with economy of scale in regards to operating economics if you want to compare the two head to head.
When you take into account the higher maintenance costs associated with ETOPS certification especially the more stringent levels required for traditional freighter routes, the 777 rapidly loses it's edge with (2) engines vs the (4) of the -8F.
Each aircraft is intended for specific markets, it is highly unlikely that either will compete against each other in revenue service.
