A massive AoE is low risk, and the world's best escape is low risk too. It could deal NO DAMAGE and would be equally strong, because it allows Kennen a 100% escape chance in any engage. Zhonya's is built to turn his low risk into NO risk, allowing him to dash into the enemy team, ult, and then have zero chance of countering him. And then because the single best escape in the game has a 6 second cooldown, he just runs away as soon as his ult is over.
