"Herc has been on a strength rollercoaster and his inconsistent abilities rely on the writer. If he fought the Thing in the same condition he did during the heroes reborn arc, wher Hulk nearly killed him, he would have lost to the Thing as well."
Wich is exactly what i said here:
"Thing has only been stronger than Herc in the first showings as mortal when he was halved."
Wich means the only time Herc has ever been weaker than Thing was after the Onslaught saga when he got depowered. And depowered literally speaking.
-Current- Herc, since the Jurgen`s Thor and the Busiek Avengers run has been written as a powerhouse again and close to what he was.
Wich makes him stronger than Ben, as the last comparation between the two was showed on She Hulk #9.
