The nice thing about Tyrannosaurus is that it's a real animal, and so we have real facts associated with it. Of course, the Rex from Jurassic Park was genetically engineered by InGen scientists, but comapred to the rest of the dinosaurs (frilled and venom-spitting Dilophosaurus, gigantic hyperintelligent Velociraptors, etc.), T. rex is actually pretty accurate. So I'm going to go through a couple of the facts right here, trying to work off of real scientific ones as well as those from the JP franchise, as people decide whether to vote for the Rex or Ghidorah.

I'll edit this later to italicize genus/species names and add a couple more points to my argument, but I hope you'll consider what I've wrote while voting.
 * T. rex may have had a maximum bite force approaching 13,000 pounds. To put this into perspective, that's the equivalent of a whole other T. rex slamming into you at full force. It's what helped it beat Tubby Soft-Squeeze in the previous round, and even though King Ghidorah is admittedly much bigger and not made of marshmallows, a powerful bite is still a powerful bite.
 * Its bite may have had a few tricks up its sleeve. Keep in mind this is a very controversial theory, but some scientists believe that the mouth of T. rex may have been a bit like a Komodo dragon - in the sense of its teeth. The chompers of both animals are serrated, meaning there are tiny grooves in their teeth. In Komodo dragons, these grooves harbor deadly bacteria, acquired due to their scavenging habits. All it takes is a bite from a Komodo, and you're dead within a day or so. Some scientists think the Rex may have had this ability. This is disputed by most of the scientists studying T. rex, but it could be considered in this particular scenario. King Ghidorah may be a giant dragon thing that beat up by Godzilla, but a big giant dragon thing can still get sick and die.
 * Corollary to the above, there is an interesting disease featured in the second Jurassic Park novel that may be of note. It's called DX, and comes from prions. (Prions are basically protein fragments.) It originated from the food that was originally fed to the carnivorous dinosaurs when they were first bred, and explained why the lifespan of dinosaurs on Isla Sorna was very limited. I don't believe its effects were thoroughly explained, but let me give you an example of another prion disease. Fatal familial insomnia is a disease that basically eats away at the sleep centers of your brain, which means that you suffer from terminal insomnia. The last year and a half of your life is spent entirely sleepless, and you basically go insane in the process. Now, DX is not officially movie canon, and I am assuming from the images involved in the competition we are talking about the movie Rex. But DX has long been suspected as a plot point for the upcoming fourth film, so it's only fair to include it.
 * King Ghidorah is, of course, a huge sonnuvabeast, much larger than a Rex could ever be. And it shoots lightning bolts or something from its mouths. But if you watch the movies involving Ghidorah/Godzilla/Mothra/Rodan or any of those kaiju monsters (the Toho ones, right? Correct me if I'm wrong), none of them seem very coordinated. They shoot their lightning bolts all around and hope that they hit something. Even when they do hit their target, Godzilla is a very big target. Obviously, this is due to the special effects being used, but as our only records of what these monsters can do, it seems that this is their regular attack style. in this respect, the smaller size of T. rex can be an advantage.
