提到總評推薦:R1 Criterion Collection
不過R3-K 版初版有送Guide book

另外內文提到

是Criterion-R1(NTSC) vs. AV Channel-R4(PAL) 的評比內容
最後的結論
Image: Criterion 勝出
Sound: AV Channel 勝出
Extras: Criterion 勝出
Menu: AV Channel 勝出

原文如下:
OVERALL: R1
For the full audio commentary and removable subtitles.
The French edition is a 2-disc set with some unique extras, but the subtitles are in French and not removable.
The Japanese disc has a sharper transfer than Criterion, but no English subtitles.
R4 has the remixed 5.1-track. For the Criterion vs. R4 image-comparison, please check this: http://207.136.67.23/film/DVDCompare2/sevensamurai.htm

Note, that new R3 Korean 2-disc LE is coming. Specs will be added, when we have proper reviews. LE has e.g. "Guide book" (Initial press only).
