The antonyms for the word "more unequalled" would be "equalled," or "matched." When something is unequalled, it is unparalleled, unbeatable, or unmatched in terms of quality, status, or superiority. If something is equalled or matched, it means that it has a comparable or equivalent counterpart, and is therefore less exceptional or outstanding than the thing that is unequalled. For example, if we say that a particular athlete is unequalled in his abilities on the field, it means that there is no other athlete who can match or surpass his performance. However, if we say that he is equalled, it means that there are other athletes who have a similar level of expertise.
