I've had far better experiences as a passenger in Y and C (I rarely fly intl F) on 767, 777, 787, and a340s than on any A380. With some airlines I actively seek out the 767 flights because they pre-date the "maximum density seating" trend, and there are a bunch of airlines where mid-life refit aircraft are better than 3-5 year old newer aircraft.

I'm much more Boeing vs. Airbus as a meaningful distinction, or which generation of a particular airline's seating system (especially in C and F) than a specific-aircraft carer, though.
