I said Orochimaru over Madara. Madara keeps his things simple meaning he's not going to kill what isn't neccissary and also he's pursuing a misguided vision of peace. Misguided but still looking for a solution even if it means total power for him. Orochimaru was just obsessed with jutsu and never dying and killed thousands at whim and used them as experiments. Madara isn't as messy
