Well, that depends on whether you believe the transformers comic or not. If you do, then they are both survivors of a previous universe that consume planets in order to live. Though admittedly Galactus seems to drain geothermal power (as well as some nebulous "life force" kind of thing) while Unicron actually consumes and processes the physical matter of the planet. Come to think of it, they may not in fact be competing for foodstuffs...
(Also according to the comic books, Primus - the God of the Transformers - was Unicron's rival in the previous universe, or possibly created by the new universe to oppose him, I forget. Anyway, it was he who trapped both himself and Unicron in planet-sized chunks of metal after the universe was reborn. While Unicron used his will to shape his chunk into a planet-sized robot, Primus shaped himself into a planet-sized planet, and populated it with many tiny robots under the reasoning that strength of numbers would prevail. Or something.)
Incidentally, here's the article I got that "pisses missiles" comment from (I linked it a few months back).
Just read it. When i saw Unicron in Toys 'r' us before christmas, i nearly bought it myself. Now i want it again. So very much. And i want my old Scorponock back, and my Optimus Prime Powermaster. And my Soundwave (he was superior)...
