Superman !
Maybe not the more skillfull neck-breaker, but him doing it was a lot more significant.
Partially because of the shockwave, but mostly because it was a big deal for him, Bane just sort of does it as part of his henchman management strategy, so it's no big deal at all. Oh yeah, Bane snapped another neck. Plus, Bane only beats up people weaker than him, whereas Zod was as powerful as Supes, and represented a threat to the entire world.
