I wasn't going to say anything but I was asking because I read technically Ritalin's active ingredient is "methylphenidate hydrochloride (HCL)" and Concerta's is just plain methylphenidate. Very, very broadly speaking I've found the fewer ingredients/features/promises made in a sold product (i.e. food, toiletries, appliances, electronics), the better. (This is just meant as a starting point to help narrow down the decision-making process obviously, and doesn't automatically overrule other considerations.)
