@kangconquers: I made no mention about how fed he was when he defeated them. Only that, 1. He did defeat both of them, along with killing their(more powerful) master, the last time they fought. and 2. He was weakened when they defeated him.
Aside from that, I mostly agree with you about Galactus, except the last part. Even at the normal levels that we generally see in the comics, his high-end feats are far more impressive than the equivalent feats of the other characters.
