In the Rising Storm story of F4, Human Torch figured out why Galactus really needs to make heralds out of mortal beings. As a Cosmic, Torch was able to see Galactus for what he is, a very highly transcended being. So high up that he's incapable of perceiving aspects of the universe that are obvious to mortals. Additionally, when Dr Doom took Galactus' power, the environment around him was being warped in his image, because his human mind couldn't yet grasp the power of Galactus.
The human mind is incredible, but its not powerful or conscious enough to instantly create another being or a planet or a star like Galactus or the Phoenix Force can. Think about it, processing all the information of every atom, DNA sequence cell, etc in a person...beings like Galactus can do it with ease. So even if someone like sentry or Jean Grey can wield more kinetic energy than Galactus, He will still always beat them because he understands the universe to such a higher degree.
