Does Mid-Woofer Size Relate to a Speaker's Realism

It could be argued that a small mid-woofer is 'quicker' in its response to signal-input and, therefore, more realistic in transient response. Is this true?

It could also be argued that a large mid-woofer is better able to reproduce the lower tones of the midrange in a more realistic manner. Is this true?

Is either choice better at realistic reproduction, overall?

[Since I do have strong views on the subject, as the O.P., I'd prefer to remain outside any ensuing discussion, as much as possible, on this one, if that's O.K.]
