Personally, I think The Shadow is a far superior game.
I looked at pics of the other one for sale to see what you meant by flipper wear. Honestly, that's a little unusual, and no, there is no "sticker" or anything else you could use to cover it up. If you can't live with it, it would be a fairly expensive thing to fix, and I personally could understand why that would be enough to turn you away unless you were getting a killer price.
Good luck on your decision!
