L>Light.
Motherfucker had some magical notebook that left no trace whatsoever and still managed to almost get caught.
Only escaped because, after being established that a shinigami falling in love for a woman is a rare thing, not once, but TWICE it happens and both shinigamis fall in love with a completely damaged and vulnerable girl who, WHO WOULD'VE THOUGHT, is completely and unhealthy obsessed with Kira, and then the Shinigami basically checkmates the entire plot when he/she whatever promises to kill L.
L played a completely rigged game with everything in Light's favor, and Light still needed the Shinigami to do the thing for him.
And then lost to poor man's L later on.
Get rekt, scrub.
