Go go creamy. I grew up with creamy peanut butter. I once tried crunchy around the same time, and spit the sandwich out. So, yes, creamy is teh winnar.
Vid, even though someone could be allergic to peanut butter, they could like the taste and risk death everytime they tasted it, technically not resisting it.
Edit: Never specified what brand. Jif ftw, though I would like to try the Reese's brand and maybe Skippy. Also, I must find some real Fluff to try one o' those Fluffernutters that look oh so tempting and good.
