polishing slabs...PCGS vs. NGC

I am wondering if anyone has noticed a difference between PCGS and NGC plastic?
I use Novus #2 for polishing, and when I use it on a PCGS slab, a couple wipes and the thing is good as new. On an NGC slab, however, the slab usually comes out worse.
Also, the NGC slabs seem to be made of a different type of plastic. It looks a little different, and feels a little different to me. Softer, maybe. Perhaps this kind of plastic is not suitable for polishing, or requires a different type of polish? Perhaps I have gone completely insane?
