My wife and I have taken both airlines in J within the past year. I would rate JL better in food, particularly in the Japanese meals. NH was decent, but I didn't feel it was as good as JL. My wife, on the other hand, didn't like the JL Japanese choices (FYI, she's Singaporean), and thought that NH's Western meals were better. However, she pretty much dislikes all airline food, so better is a relative term with her.
