I don't recall Hulk ever sh1tting his pants when Thing comes rompin and stompin up into his grill.
Hulk has rarely gone all-out against Thing. The few times he arguably did, he nearly killed Thing in a cliffhanger where everyone thought he died, he collapsed his ribs in a single shot when he thought he was fighting the ghost of his father, and he put him down with a single double-handed clap to his ears.
On the other hand, Prime basically has never held back against Conner. Mostly because he isn't experienced enough to do so. That was his curse. Prime only ever arguably held back once in his post-Crisis career, per his words: when he ambushed Conner in Smallville. Thing is, Conner was supposedly holding back as well. So, not analogous to the Hulk-Thing feud at all.
