I think it's more the finish you get from Pam. Black as night, and shiny. From a collectors stand point, I believe the appearence is what matters. Not all C I has survived that well, and pam at least leaves it looking better. I've used crisco before, and the finish just isn't the same. I know there are some on here that use mineral oil, if they only plan on displaying the piece, but if the situation arose that I would need to use a certain piece from my display, I would have to scrub it down, or electro it , and season it in order to use it. I assume that any if not all of the piees I sell, are going to be used, so I season them with the best method I know for a piece that's going to be used. Just my opinion.
