On a long-haul basis, I flew on the A343 in J from CDG-PVG once; the IFE movie selection was sparse, the food was fine, and the service was friendly/attentive enough. I don't remember anything from the flight, so take that as a positive or negative, depending on how you view these things.
On the short-haul flights (3 and 6 hours, respectively, on 738s, I felt taken care of, and being 1 of 2 passengers in J helped.
). There wasn't any IFE that I can recall... it was a red-eye, though.
