In such a case, I may agree on this.Definitely jpegs... I was shooting with someone at the school's orientation in the field facing the sun... the other guy overexposed and the washout was terrible... while I also overexposed, the colour vibrance was easily much better... I notice that the Canons don't handle high contrast colours very well... everything gets normalised so that the overall image tends to look flat... at least that's my experience so far...
