Death Note is a classic example of an anime with smart protagonists and antagonists fighting an incredible battle of wits. The story pits the genius Light Yagami against the world's best detective, L, with both of them battling it out to catch the other and prove their own brand of justice superior. Anyone who loved that high IQ anime can find plenty more to love, too.
