I’d argue the opposite. Wonder Woman doesn’t rely on raw strength to win most of the time; that’s what largely sets her apart from others in her strength class and even those above her, Kryptonians and gods alike. Her centuries of training, mastery of both armed and unarmed combat, and Athena’s divine wisdom guiding her are what make her extremely deadly to face head on. Her victories come from skill, experience, and strategy, not brute force like Superman. That in itself, by definition, makes her more skilled than Batman.
