If you'll note the following panel, Galactus' body posture is unchanged. He looks completely unphased. He doesn't state--doesn't even hint at--how he had to "will himself back".However, if we're going to be liberal in our interpretations of artwork, note Darkseid's stance after he blasts Galactus: he seems taken aback.
Yes, the crossover wasn't canon. But for what it was, Galactus--who hadn't even fed yet--was clearly the far more powerful being.
