The T-rex is way better but it's absolutely terrible how they have the whole T-rex just kinda swing out like a pinata over the drop and he just floats there in the air with his legs with no grounding. The one overhead is really awesome though. The snake is more believable in place but not as thrilling, IMO.
I think that the T-rex would be more thrilling if they did a better job of hiding it, maybe with some mist. The fangs of the snake are totally unexpected, but when you see the lowered T-rex behind the water, you automatically know why it is there.
