I buy generic natural PB...basically the same as Smuckers brand. Right now I have one from Whole Foods, but any store brand generic is good. It's just peanuts and salt.
I only use 1 T so it's 100 calories...not too bad, it fills me up well.
I didn't grow up eating Jiff or those types, so they taste weird to me - not like peanut butter "should" taste in my mind. Plus a lot of them have hydrogenated oils added along with the sugar...my fiancee will only eat this type of pb, and I found the Whole Foods 365 brand doesn't contain hydrogenated oils...and he approves of it. LOL, which he didn't for the Smart Balance or the natural ones I buy.
I have tried the Better Than Peanut butter stuff. It is crazy expensive and it is runny...other than that, it tastes pretty good.
