Whether you like the marshmallow creme fudge or the "good old days" fudge is just a personal preference. I like them both, but I'll have to say, I prefer the creaminess of the "good old days" but it makes my arm just about drop off stirring it. That makes the ease of the marshmallow fudge look really good. If you use really good chips like Ghirardelli, it helps somewhat.
I've had cheap chocolate chips fail in this recipe, I got them at Big Lots, thinking "How bad could they be?" I think Texan got it right...they have waxes or something in them, they tasted odd and insipid, and had a mouth feel a lot like those old wax lips candies.
