i don't think phyrrus is a very good candidate as he is the inventor of the Pyhrric victory
caeser, alexander, marius, henry V, saladin, baybars, el cid, ptolemy, seleucus, assorted diadochi, scipio africanus.
personally i think caeser had the charisma to, if he had equal amounts of men with equal armour and arms, nurture good enough morale to win.
so Gaius Julius Caeser wins!
