They taste better probably because they are slightly more perishable and therefore had to be sourced closer. The same strawberry could be grown using conventional methods to taste as good or better. I think it's just supper hard to differentiate good tasting berries from bland ones when the good tasting ones look the same or uglier and thus get the price premium. It's strawberry season BTW go out and pick some local ones. The farm fresh ones will blow you mind. No need for organic
Maybe the question should be more about heirloom v conventional? Most conventional veggies and fruits have been bred for packaging and aesthetics over flavor. Consider the conventional tomato. It is bright red, has a thick skin and is shaped to perfectly fit in a packaged box. It tastes like water. Conversely, Heirloom tomatos are oddly shaped and multi colored and taste so much better. But are harder to package and sell.
