Banshee's lets you walk through the stun wall without caring.
Champions with blinks can also go through it pretty easily.
I personally like Leblanc and Katarina against him. He can't trap Kat in his stun wall and Leblanc can just W out of it while it's forming (or have him form it around her after she W's in and then W back to it) without caring a whole lot.
Champions who can outrange him, when played well, are also really good against him. Someone like an Azir can keep soldiers on him with Rylai's and kite around him for days until he dies, or someone like Aurelion Sol with Rylai's booping him with the stars.
Final recommendation is Fiora. Why? She can use W during her Q dash. As a result, she can dash into the stun wall, block the stun, and then stun him instead and use it as a mini gap closer (especially if minions are nearby for her to hit with the Q to get the cooldown reset).
