This. Jack Horner is also biased against T. rex. Spinosaurus was mainly a piscivore. It wouldn't have been able to fight a Tyrannosaurus like that.

The real Spinosaurus, despite being huge and powerful, was probably quite slow on land. Also, while it was bigger (at least in terms of length, and probably weight) than Tyrannosaurus, T. rex was likely much faster on foot and and had a stronger bite. In Jurassic Park III, it's depicted as the ultimate superpredator who eats T. rexes for breakfast. They also enhanced Spinosaurus in terms of durability; it easily breaks out of a T. rex bite to the neck in the opening moments of their fight, and is not in the least hampered by the wound. In reality, such a bite would've been crippling, if not instantly fatal to pretty much anything.

Horner was proven wrong in a way that likely irked him: T. rex was a carnivore, it was an opprotunistic eater. Scavenger or living prey, didn't matter. It ate it all.
