1. Size does matter, because T. Rex would have been intimidated by such a bigger theropod, and would be less prone to attack and more prone to run away.

2. Sure, not whiplike, but thin and flexible, allowing for quicker turns than T. Rex.

3. Again. Faster. A person on a bike could easily get away from a T. Rex.

4. Giga would definitely tear out a huge chunk of flesh. That's the whole point of those teeth, silly. With its bigger teeth and bigger jaws, it would have torn out an even bigger chunk of flesh even more easily that T. Rex.

5. Ok, maybe not crests, but Giga could definitely knock over T. Rex, rendering it helpless.

6. Giant theropods did have to use their arms to get up. What else would they get up with? T. Rex's arms are so stubby and useless, that by no means could it use them to get up. Giganotosaurus's arms, though, were much longer, and armed with bigger claws.

No, T. Rex would have had to get really close to Giga to bite its spine, and that doesn't make sense because Giga was faster and more agile. So, Giga would be the one running down and devouring T. Rex. If Giga bit first, which is most likely because it would see T. Rex as a prey item, then T. Rex would go into shock and suffer from extreme blood loss, making it incapable of any further combat.
