I've been blessed to have great crews on all my intl flights, but you're not alone in noticing the difference between sUA/sCO. I've read those threads.
The 777 is a 30 year old design, if you ran the higher pressure and humidity of the 787 on it, you would get heavy condensation and rust in the belly of the plane and eventual hull failure due to over-stressing the hull. Carbon fiber on the 787 and 350 (and now the c300/c100) allows the higher pressure/humidity.
OP, if you are 5'8" I would take the 787 and take a middle seat (which are in effect all aisle access). The higher humidity/pressure + HND being an hour closer, IMHO will make up for the better seat on the 77W. OTOH, I am 6'2" and the sCO seat on the 787 (and the 763) is too short for me, and not comfortable, so its not really an option.
