Kage is not a position determined by strength. It's decided by one's capacity to lead. Suigetsu is the worst leader out there, whereas Chojuro had shown some resolve and capacity as a ninja and could easily bloom into a ninja. Being a Swordsman in the village of Swordsmen would also give him some respect.
