Let's see...
Einstein: Nobel Peace Prize winner, developer of the theory of relativity and mass-energy equivalence formula (E = mc2), Time magazine's Person of the Century (beating out Ghandi and Roosevelt), numerous other awards received and named after him, etc.
Arias: Journeyman waitress who drifted from job to job, leached off people for money, housing, etc., slaughtered ex-boyfriend in cold blood, delusional sociopath who will be put to death.
I'd say its a damn close race between these two individuals in the grand scheme of things. Besides their IQs, they certainly have lead parallel lives.
Slight edge to Einstein because he had better hair.
