In the post i already quoted, i gave a blatant example of Eclipso amping who he possesses.
He possessed a normal woman, who kicked a giant luthorcorp Kryptonian battlesuit off a rooftop building in her bra and panties, while barefoot.
And in this same story, Marvel stalemated Superman who was possessed by Eclipso, who earlier had amped that woman.
And Captain Marvel stalemating an Eclipso possessed and amped Superman is fighting a Superman under mind control basically.
You've been debunked on two claims.
One, that the Marvels have never faced a Superman under mind control, and two, that Eclipso doesn't amp his hosts, tho he clearly amped the woman from the same issue earlier.
Case closed.
And while Marvel cannot decapitate Superman, he's managed to Ko the guy twice...to Wonder Womans none.
And Underworld Unleashed, where Cap with a broken arm took down a group including WW and J'onn.
Cap +1, WW +0.
