In Grixis i'd vote for Kess, Dissident Mage. A while back i did brew a list around her for a friend that revolves around (pseudo) wheels, Mana Geyser+Comet Storm type effects and a lot of control-ish effects. It is very fun to play against, results in heavy decision making and still isn't as oppessive as similar decks.
Rashmi, Eternities Crafter is another awesome control commander. Powerful colors, built in CA and a lot of fun/decisions playing it, due to top deck manipulation. Be cautious though, cards such as Forbid, Capsize and others might create very unfortunate situations and soft locks for your opponents.
Mah boi Talrand, Sky Summoner is solid classic for said archetype. Pseudo storming, swarming with Drakes all through mono-U control.
Notable mention should be Ephara, God of the Polis. WU is a solid control combination and due to her tech i always enjoy facing it.
