Even if we ignore the body proportions the figuarts are objectively better based on the accuracy of the suits. Look at the diamonds on the chest/gloves/boots here
>>6313339 then look at pic related. The shape of them on the legacy is all wrong. The morpher on the legacy is twice as big as it should be. The belt lacks the trim, while the gloves and boots have trim around them that aren't present on the suits. And then there's those shoulders. The legacy figures are just all around off-model.
