Depends on the comp, and the difference in lease prices compared to the price of fuel. The 772 burns less fuel per passenger than the 762 or 763, especially when they both have the same type of seat. You also need less staff & slots per passenger. 773 is better again on fuel & staff/passenger. Round trip times are roughly equal at 5000 NM. 767 is quicker if it's shorter thanks to shorter turns, 777 is faster if it's longer thanks to quicker flight time.
So if there's no comp, and fuel is expensive enough and/or you own the planes, 772 & 773 will be better than 762 & 763. If there is enough comp so either plane will get roughly the same number of pax on each flight, or if fuel is cheap & you're leasing, 762 & 763 will be better. 764 will likely beat them all, but don't have exact stats handy.
