Personally I believe it would be a big improvement and sway me to slab more cards in an SGC holder. Overall, I prefer the BVG holder & their sub-grading. I don't prefer their high grading prices.

SGC could pummel the rest with sub-grading corners, edges, surface, and centering. The one other thing would be to have an inner-sleeve to protect the card, but I don't see that happening anytime soon. They'd have to redo the black framed insert (looks like that thing would affect the card over time).

Enjoy your collection!
