I was very surprised when I read that the US Games green box (not greenie) and the AG Muller Blue Box decks were the same deck, different boxes. I had (and have) a green box which I love very much. I bought an AG Muller one to trim and was surprised at the difference in cardstock. Both were the same size and there was a noticable difference in thickness. I think that there are varying degrees of thickness, not huge differences, but enough for obsessives like us to notice it
Lamination I haven't noticed. I think it is very light and "just right" on the copies I have (and I have a quite a few). AG Muller cardstock and lamination is, overall, very good. My older Weiser A has very thick cardstock but, like Abrac says, the image reproduction is not so good.
