After a two week utterly informal comparison test, I have decisively concluded that organic bananas do indeed taste better than the usual, much better. 29 cents each vs 19 cents at Trader Joe's. I focused in on the organic bananas because their texture was firm, their flavor not icky and cloying, and one had the sense that these were fruits that had not traveled thousands of miles in refrigerated ships and trucks, though of course, they must have.
It's well known that commercially grown bananas experience their share of herbicides and pesticides, as do the people who work with them in the fields and pack them in the sheds. That alone makes the move to organic--only a dime more per banana!--the appropriate choice.
Along with the taste.
