Tyrannotitan is larger, but is only slightly lighter than the combined weight of the Gorgosaurus, it can still win.

I'd give an edge to Tyrannotitan too. The weights are fairly similar, but it should be able to take several bites before going down as well as kill a Gorgosaurus in 1 bite. It's also quite robust.
But not a mismatch; if the tyrannosaurs can inflict damage and stay out of reach of the carnosaur long enough, they could well win.
