Obviously it's a mixture of all of them. If both foods have the same nutrients, look and taste the same, but one tastes like crap and the other like roses, guess which one is better?

I wouldn't eat tasty poison, just as I wouldn't eat very nutritive food that tastes horrible. A balance must exist, and those that have better taste, more nutrients, better appearance and better smell will be the ones that are "better".

Balance is the keyword.
