a prime henry armstrong or a prime benny leonard

I would favor Armstrong. He had a workrate that had never been seen before, remarkable physical strength for his size, and amazing reserves of stamina that allowed him to keep up his close quarters, high pressure, non stop style for as long as it took. On top of al of that, he had extremely quick hands and reflexes and underrated boxing skills, including the kind of head movement that made him a hard target to tag. Fought in a more talented division and has the perfect style, tools and punching power. He would be too much.
