age is not an issue for either, as they are within 7 months of age
size doesn't seem a great issue, as tyson/ff are 19.6 guys & short & i'd throw ato in, who shouda run 19.6 in late '90's ( i believe his 19.77pb followed a quick 100m a coupla hours before )
extra height gives you the exra stride length, whilst short gives you the extra frequency
as
time = stride * frequency
i woudn't say that one has greater clear-cut advantange than the other
