I don't know how anybody can sit through Ricardo Montalban's performance as Khan without feeling the need to vomit. It's easily on the level of Palpatine in the later part of ROTS.

Knife in the heart! He was an actor of his time. It was just so clasic how he did it. His performance could just take me back to so many great T.V. villains, that Montalban's Khan became a combination of them all. For me, that made him become that much more of a powerful foe for Kirk. Ricardo Montalban just had that X factor. I can't put my finger on what it was, but it worked for me.
