Original. Director's Cut ruined the vibe and vision and was a cashgrab forced on Kojima by Sony.
He himself has said it's not a "director's" cut because he didn't cut anything from the original game and didn't plan on making an expanded version.
Make sure you get the Steam version because it's the only way to play the original on Very Hard mode, the only way to give the game even an iota of challenge.
