The Crazed Scientists

At last, I continue my Face-Off drawings. My last one was a sexy face-off between Medusa of Soul Eater and May Koon from my own manga. Now we have a mad scientist face-off between Franken Stein of Soul Eater and Mayuri Kurotsuchi of Bleach. Which do you think would win? (Please state and explain 'if possible' in comment) Enjoy.
