Pretty sure it would be A350, or B787, or one of the latest gen updated B777's. Basically stick the latest generation biggest super high bypass turbofans on a modern body with lots of composite construction to minimize weight.

Soon the 777x will be out which should be the one to beat then. Last I saw they were running into some issues with the GE9x engines which are massive.
