that first line would make no sense because you can not compare lunarian mihawk with mihawk
but you can compare enhanced lunarian jinbe with jinbe
and he is much stronger without a doubt, feats can tell
sanji apparently just hit the seraphim so he can not feel intimidated when he does not even know what the hell just hit him
see, sanji hit lunarian jinbe and apparently made him spit blood, blackbeard did no damage to a seraphim, why did not anyone pointed that out...
