I prefer not to eat growth hormones, antibiotics, artificial colors and flavors, preservatives, etc. Organic also tastes better. Try eating organic potatoes for a couple weeks and then eat a "conventional" potato. The difference in taste cannot be denied.
My daughters especially noticed the difference in taste in beef and baked potatoes when they were teenagers who couldn't have cared less what we ate as long as it was food!
We try to support the organic producers, primarily because we do not like ingesting nerve agents, growth hormones, and antibiotics. It is very hard to grow certain food organically, so we don’t mind paying a premium so that those farmers who take the risk of bringing organic food stuffs to to market can continue. Examining nutrient content without addressing contamination from these other nonfood substances is a convenient way to belittle the organic food movement. Organic certification is another issue, one that is hurting the little farmers and keeping them out of the market.
