OVERALL: Draw

Between the US Complete Collection, for the additional commentaries and wealth of extras on its bonus disc, and the US Target Exclusive for its exclusive additional documentary.

Note that there is a UK Amazon Exclusive that appears to come with the same bonus disc as the US Complete Collection, as well as a 16-page episode guide, a reproduction of Don Draper's "Why I'm Quitting Tobacco" letter, a letter announcing Sterling Cooper + Partners new logo, headed notepaper, art cards and an SCDP office plan.
However, it should also be noted that the US Complete Collection appears to be the only release worldwide that adds commentaries to this season.

This title has also been released at least in the UK by Lionsgate.
