OVERALL: Blu-ray ALL

The US Complete Collection for the additional extras.

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 features to an existing season: adding commentaries to Season 6.

This has also been released in Holland by A-Film but we were unable to find full and reliable specs. If you own this release or have a link to a review (that includes a disc breakdown), then please let us know via our forums.
