I have flown the new F product on four sectors with the 77A and like christep, I have not been annoyed inside the cabin by the factors listed by the OP.
I do slightly like the 74A (which I have also done the new F product on several times already) over the 77A for several seats that enjoy "location advantage" which cannot be experienced the same way on the 77A as I discussed in a past
thread. But by no means is the 77A an unbearable experience.
