I have had occasion to ride a 787 a number of times. When flying on that thing, wifey and I pack inflatable butt cushions that we blow up just before taking our "seats". The thing creaks and squeaks like a plastic bucket even when lightly loaded. Flashy window blinds don't hack it for me. The only marginal alternative would be a 343 config 777.
Admittedly not all airlines have the same seat setup, but on BA, I would take an A380 over anything else on long haul. It helps that we are able to travel PE or Business. Still as I say, no one wants my opinion, it's not cost-effective enough.
As for gushing, well I hate flying anyway and only endure it because there is no other way to reach my destinations, If I had the time and the money I would go by ship.
