A 'giant' with deadly 'kung-fu' moves and 'mecha mecha no mi' abilities, wielding a 'scientific' gunblade, also happened to be mastered 'haki', 'rokushiki' and some 'other abilities'. (sorry, couldn't resist :D )

For an actual comment; haki and rokushiki are both great but I would choose Haki. It feels more badass.
