I am now living in the ETOPS world, but over a lot of not much I will take the 74 any day. No amount of log book ink is going to replace engines/generators/hyd systems 3 & 4!
I’m not debating 777 vs 747. They are each meant for a different type of leg. I’ve flown both. The 747 still wins the coolness contest.
Boeing does not build aircraft that compete against each other. Think of the 777F as a Ford F-150. Not every job requires the increased load capacity of the F-250 (B744) or a F-350 (B748).
Also remember as you add additional systems and engines that the statistical odds of having a problem increase.
