Lets see if you are right, Christian.
Attack: Rhedosaurus, as its value is 0.3898 tons of TNT while (correct me if im wrong) Kong is seemingly calcless and is therefore baseline at default, so 0.25 tons.
Durability: Rhedosaurus, see attack.
Lifting Strength: Equal, as both are K.
Stamina: Equal, as both are very high.
Range: Rhedosaurus, as it has hundreds of meters of range with its size, while Kong is smaller and only has several dozens of meters of range.
Intelligence: As unintelligent as they are, Kong has this, as he is at least sapient of what hes doing unlike Rhedosaurus, who is Animalistic. Kong can be skilled when using his surroundings as an advantage, so he can surely try to take a skyscraper and throw it at Rhedo.
Experience: Rhedosaurus, as its 100,000,000 years old, so it has WAY more experience in its life compared to Kong, who is only 40.
Abilities: Rhedosaurus. Its shown to have a better Regenerationn (Low-Mid > Low) and while Kong would resist Rhedosaurus' blood poisoning effect via Immortality 1, he cant really kill his opponent even if he tries to hide due to its opponent having more durability and better regen.
Well, I guess despite Kongs intellect, thats literally it. It has no way to kill its opponent due to regen and durability, and not to mention, Rhedo has the range due to being much bigger. So, voting Rhedosaurus.
