Of the two edges that Pudding sent you, the synthetic edge should have a bright mirror polish whereas the Jnat edge should be hazy. That hazy finish is a result of different particle abrasive sizes and the manner in which the binder carries those abrasives in suspension. Internet wisdom to the contrary, man-made controlled abrasives allow apex refinement beyond what natural stones can do. You don’t see modern optical systems polished with Jnats. If the synthetic edge he sent was duller than his Jnat edge, he could have refined it more. If it was harsher feeling, then it may have been refined too far (a mistake I often make).
