When my dad was in the camera business, he saw some actual research---I think it was published and everything---that found that, in (very) general, Fuji's colour films were deemed more realistic than Kodak's by Japanese viewers, and the reverse by American viewers. (I don't remember if it was specific to either print or slide.)
So I think you're saying that the British are more Japanese than they are American?
Personally, I find Provia 100F to be nicely realistic, but everyone has their own taste in these matters. People really do perceive colours differently.
