There was likely a vast difference between Superman pre-Zod fight and during his fight with Zod, as the latter was punched through several skyscrapers whilst suffering no external injuries. He also flew through the World Engine whilst heavily weakened, a feat that's easily beyond City Block level. Thus far, MCU Thor and Hulk haven't shown themselves to be much higher than Large Building Level, so the only advantage they truly have over Supes is Thor being debatably faster than him when at full power, as well as Hulk having mid-tier regeneration.
