Hiro disk has a lot more usability than just countering Cheshire. Most heroes have good enough evasion and tenacity to occasionally dodge status effects and to reduce their length by a decent amount. Reducing those stats by 75 is more than enough to make whatever they have left completely useless.
Technically, it would be even better for countering Max, since you can prevent him from using his white and gaining the BD buffs in the first place.
