From my opinion it's a long, brutal, prolonged and bloody good fight literally but it comes down to circumstances. If there is a lake or river or a good  source of water nearby then Spinosaurus has a good chance. In a dense place like a forest then the I-Rex would have the element of surprise and could overpower the Spino but from what has been seen from the third movie the Spino would break free. The Spino would attack the Indominus's neck and it could easily lock it's jaws on like it did with T-Rex but I can't say what happens from there.

For defenses it's close between the two but I think that the Spino just takes it because of its sail.
