I took this flight earlier this month and preferred the J seat over the old Club World on the A380 due to the direct aisle access for every seat without having to crawl over anyone's feet to get out. Had you been in the Club Suites or more importantly F, then I might put up a fuss. If you have flown Iberia J, the seat is either the same or very similar to what Iberia offers in J. I found the crew to be excellent (wife and I each got thanked for being oneworld emeralds which I can count on one hand the number of times that's happened on AA/BA) and the food/bedding/drinks is what you would find on a normal BA operated flight.
