There were reports of minor differences between identical cards that are pulled from Jumbo-Packs rather than Slim-Packs.
In Jumbo packs, certain cards with texture (Full arts per say) tend to have more "sparkle" to them compared to Slim pack cards. They look more like Japanese cards in this matter.
On the other hand, certain cards from slim packs may look more saturated and brighter which makes it less sparkle but allows a bit of "POP" design.
Do keep in mind that all S-Chinese cards are printed in Japan and these differences are not officially acknowledge by the Pokemon Company. These statements are mostly based from reviews and self-experience. If you're interested in just the art, do give them a try!
