Chunky peanut butter is better than smooth (unless the recipe demands otherwise, of course). I like peanut butter because I like peanuts, dammit. I also prefer fresh peanut butter to that Jif crap. Having to stir it to mix the peanut oil back in is a small price to pay. The only ingredient in peanut butter should be PEANUTS.
I like chunky style because all peanut butter has an FDA approved limit on how many bug parts a jar can have per gram, and it makes it easier not to think about what that crunch was.
