He gives the most reward (While Zhloe/Kurenai/M'naago all give the same since the last patch that put them all to the same level)

This is, bearing in mind, once you get reputations maxed out.
You only need to unlock Zhloe to get Adkiragh, not needed to complete all Zhloe’s quests. I’ve completed Adkiragh but yet to complete Zhloe.
