By contrast, I studiously avoid the 764 because the short seat and restrictive footwell make it impossible for me to get quality sleep. 788/9 is okay so long as I can get a bulkhead; otherwise footwell is too restrictive.

Big picture, I love the privacy of the odd-numbered window seat on this 77W. Slept 7 hours last trip NRT-SFO. The downside is now I don't want to fly any other UA seat.
