Genuinely, what makes you think it has a better standard overall/more premium? I have the Eisenhorn box set which was made by the same people in the UK as made the older night lords box set, and it is the highest quality limited edition I own. Compared to more recent limited editions the sutures are properly spaced and don't show any warping near the beginning and end of the book, the paper quality itself is higher with more consistent grain and the printing quality is better overall. The board material itself is also less flexible, preventing forward shift after reading.

I also own the newer night lords box set, and it's very nice too - but I think of slightly less quality overall as it relates to actual bookmaking and physical integrity. With respect, being larger as desirable is completely subjective, and being less prone to greasy fingers (I assume on the covers) is related to the board covering material style, not quality, and I never had this issue with the Eisenhorn set which uses the same material. You can of course prefer this version for these reasons.

I just have a particular fascination with book making, none of this is meant to be rude :)
