Oh, and the 767-400 is a mess. Only two airlines ordered it (I think). Part 777 avionics and longer landing gear aside, its a compromise of an old airframe. Not good.
You don’t seem to actually know much about these aircraft
The only similarity between the 727 and 757 is the fuselage diameter, there were thoughts of incorporating a T tail early on, no aspects of that design carried over to the production 757, it is a totally different aircraft with a new airframe and systems
While the 764 was not a big seller it’s been a sterling and economic performer for Continental, United and Delta, it’s a profitable compromise
I have a number of years on the 727, 757 and 767, your ‘analysis’ is incorrect
