i have always found the service on NZ better. The meals had better options. The thicker mattress was more comfortable, although it was always a little awkward as they wanted to make up your bed.
I think the AC timing of several hours later is better for a night flight , unless you really want that 5.40am arrival for some reason. It was okay for me, as it meant arriving at my mothers at 7.30am on the Shore each Christmas eve, but not that good for most tourists?
