Hawking or Yang Zhenning, who has made greater contribution to science?

I majored in physics in college, and now I am a physics teacher in high school. Personally, for reference only, I think Yang Zhenning's academic achievements are far greater than Hawking's, and Yang Zhenning's physics academics are groundbreaking and leading, far from being comparable to Hawking's.

I admire Hawking very much, but I prefer to call him a "physical philosopher". His cosmology is a bit metaphysical, as if he were gambling. He gambled that he was right, just like a fortune teller said that someone would help you in the future. Well, Hawking's cosmology will be proved to be correct at some time in the future, and Einstein's theory of relativity will only be more perfect and aesthetic. Its academic research is not pioneering and leading, and it still lags far behind Yang Zhenning.

When it comes to the pioneering and leading theory of physics development, Newton's classical mechanics, Maxwell's electromagnetic theory, Einstein's theory of relativity, quantum mechanics formed by physicists such as Bohr, Dirac, Heisenberg, Schrodinger, Planck, De Broglie, Bonn, Iordan, Landau and Feynman, Yang Zhenning's field theory is pioneering and leading, guiding the direction of physics.
