i think both are about even in power, sorry but Trinidad damaged his opponants how bad he would hurt them, chin i'd have to say goes to Trinidad, even though he was shaky, he was only KO'd once, and wasn't completely out at that, Trinidad would go down more because of his balance than because of his chin, Hearns takes it on boxing ability Trinidad had some boxing skills but Hearns had better movement, jab, and speed, not that he was faster, but his combos were just smoother, and mixed up more than Tito, either way i'm sorry but just cause of the power it would be a 45/55 fight for Hearns, but not by much
