What settles it
Senku starts from zero. In a world with no industry he makes medicine, chemicals and eventually far larger machines by working out each step and building the tools for the next. His knowledge spans chemistry, engineering and biology, and it almost never fails him.
Tony's best feats are just as strong in one respect: he builds the first version of his suit in a cave from scrap, and builds a new element in a workshop. He has more resources most of the time, but he also solves harder theoretical problems in a shorter time. What holds him back is impulsiveness and a habit of solving the wrong problem when he is angry.
The main caveat on Senku is the story around him. It supplies him with recipes he could plausibly remember and materials he could plausibly find, and it gives him time. That keeps the gap small. Senku edges it on breadth and reliability, Tony on raw ingenuity.
