EX isn't a high rank, it's a special rank. It denotes irrationality of a non-feral nature.

For Vlad, it's because he accepted the legend attached to his historical self fully. It's insane to accept such a thing, but he isn't mad enough to turn into a beast like his Lancer persona would when activation Legend of Dracula.

For Kiyohime, it's because she is an extreme yandere and stalker. She is madly in love, and rationality is beyond her thought process. Actually, I would have gave her E++ rank at best, but EX conveys the idea better, I guess (and helps with damage).

For Spartacus, it's because he is naturally similar to a feral beast. Getting any kind of Mad Enhancement won't change his mutinous and violent behavior. He is a real berserker, thus his rank is abnormal. I bet he would have a C rank and above M.E. if he was summoned as a Saber.

For Nightingale, it's because her devotion is beyond human comprehension. To everyone, this level of selflessness is irrational. She isn't a beast, but she has blurry limits like a normal Berserker would. Therefore, she is EX. I bet she would be a far better Caster, but being summoned as a Berserker allows her to do her job in extreme conditions I guess.
