Quality wise, i'd say the Future Shop SB. In terms of looks, other than the Target release, they're all the same....so my decision would have to be based on the slipcover. In that case, for me, it's Korea.
The Digipack from Japan with the full slipcover is the best for me.
Not a Steelbook I no, but as a complete package and beautifully designed that's my favourite !
