I really enjoy the "chronological order with the deleted scenes" included. But a close second is the theatrical version. What makes the chronological with deleted scenes so great is that it provides all of the little background that the theatrical version was forced to leave on the cutting floor. It makes the whole story appear more complete. For example, two key deleted scenes come to mind that would have put the first film in sharper focus: when Sonny does the inquiry about whether Clemenza or Paulie "sold out the old man" and the scene in which Michael decides to get involved. The notion that Clemenza was considered a traitor in the deleted scene would have given the theatrical version a different twist.
