I have both the 1964 movie and the 2000 made-for-tv on separate DVDs. Both are great productions, if for different reasons. The original movie was made during the Cold War, and hence, may be more dramatic for those that lived it. The made-for-tv version adds the intensity of a live production and more modern production techniques. I can't say, in my mind, that one is better than the other, they are just different. The actors and crew in both versions created a compelling production with thought provocating consequences. Buy one, buy both, either is worth the experience.
