Which way should I store my PDS saga discs in the sleeves?

I always place the discs that are in the sleeves label side down, but I was wondering if I should place it label side up because I heard the label side gets more screwed up if it gets scratched. should I flip the sleeves?

I use something called cd skin to protect my discs. It’s a clear cover that surrounds the entire disc. And you can still play the game with them on the cd.
