If you put all the sweet spices into a battle royal, clove would win every time. Cardamom would be afraid to break a nail. Allspice, usually a supporting player anyway, wouldn't stand a chance. Nutmeg, perhaps, would put up a fight, but its strength is so fleeting it'd tap out in the first ten minutes. Clove is definitely the brashest, bossiest spice you could put in your gingerbread.
