Probably because of all the advantages given to the T.rex. Since T.Rex was: Bigger(barely), stronger, smarter, more agile, stronger bite, better senses (although I doubt that would be a major player in the battle), etc. In my opinion the battle would be closer than what others think however. Tyrannosaurus was a powerhouse, Giganotosaurus was a speed fighter. Both are useful in their own right. I'd say the battle would be around 49-51 to 70/30 in favor of Tyrannosaurus. Both ANIMALS are cool. Answer from Tyrannosaur_5678 on reddit.com

The Tyrannosaurus Rex lived in Northern America. They lived in different time periods, but they both lived in the Cretaceous. Fun fact: The Tyrannosaurus Rex is one of six dinosaurs called with its specific name.

Since everyone else is replying with mostly text, I'll make a thread of some visual references to help you get the picture a little easier. Orange skull is T. rex, red skull belongs to Giga. Best way to describe their differences verbally is that I guess like other carcharodontosauridae, Giganotosaurus had a "D" shaped skull (much like their teeth) whereas T. rex had a more boxy, almost robust looking skull. If you've seen Jurassic Park's logo then you already know what a T. rex skull looks like, as that's based on a very well known fossil specimen, AMNH 5027.

September 19, 2021 - The skull of Giganotosaurusis a far contrast from that of Tyrannosaurus. Its teeth were sharp and serrated, and rather thin compared to that Tyrannosaurus. The skull is lacking the reinforced and fused joints that are found in Tyrannosaurus and its bite force reflects that difference (estimated to be only one third of Tyrannosaurus’s).
