It is impossible to know for sure since both animals are extinct and they both lived during different times and in different places. T-Rex's bite force was much stronger, but a good bite from Spinosaurus could also kill. Spinosaurus was larger and had powerful forearms, but T-rex was more muscular and heavily built. A lot of people have their opinions, but the true answer is the winner is whichever dinosaur attacks first.
