Actually, gigas were much bigger than rexes irl and possible more physically powerful, even though rexes had a very, very powerful bite force. The giga may overpower the Rex through its sheer physical strength and size compared to the Rex. I’m not entirely sure, it may be 50/50 or 60/40 for either of them, I’m not sure, I’m making a guess out of all the knowledge I’ve got.
