Nice comparisons and as the hobby matures even more the cards are being sold more for their attributes than the opinion a TPG puts on a label. For me, the most important thing a TPG does is it gives me an expert set (or more) of eyes to catch alterations. I realize imperceptible-to-the-naked-eye wrinkles can be found too, but that isn't my main requirement. I guess if I collected high grade it would be.
