I mostly agree, but I have no experience of the A380 and I don't think the 767 is that bad, not very different from the old 777. Even the IFE is old but works and I've seen worse (however, my last BA 767 flight was a BWI-LHR on 2013, so maybe they are in noticeably worse condition now).

I too, have avoided the 787. In general, all of the other planes are adequate in Y in terms of seat. Some of them may be more or less disappointing depending on how much you value good IFE or in-seat AC power, but they are all decent in terms of comfort. However, the 787 really seems to be in a class of its own due to the very narrow seats and it's the only one to be avoided, even at the cost of a more inconvenient routing.
