Ceratosaurus nasicornis vs Utahraptor ostrommaysorum

Ceratosaurus wins, its far more robust, has a stronger bite and is probably much heavier due to the dromaesaurids gracile build.

Ceratosaurus nasicornis isn't that robust, it is but not a lot. Utahraptor ostrommaysorum also has a very strong bite, considering a paper says Deinonychus antirrhopus had a bite about as strong as an American Alligator's bite. Both are around the same size as well, the dromaeosaurid is ~500-600kg (and possibly 700kg), while Ceratosaurus nasicornis is probably not much larger than that.

Shit I was thinking of Ceratosaurus dentisulcatus lel

I have seen a book written by paleontologists(some field guide or something along those lines ask raptor for it) that said Ceratosaurus nasicornis is around 600kg which I agree with.

Ceratosaurus dentisulcatus would simply dominate here, being 3 times larger than the smaller figure of U. ostrommaysorum, and 2.1 times larger than its larger figure.

There is also a possiblity of Ceratosaurus nasicornis being just a juvenile of Ceratosaurus dentisulcatus which seems pretty likely. But not official.

Yeah, I told you about that today. Many immature dinosaur specimens are kind of "gracile versions" of their adult specimens, and Ceratosaurus dentisulcatus is pretty robust when compared to the smaller species within its genus, C. nasicornis.

It seems very likely that Ceratosaurus nasicornis was a juvenile synonym of Ceratosaurus dentisulcatus, since they have fairly similar anatomy apart from the fact that C. dentisulcatus is substantially more bulky.

Ye, it looks pretty much like a sketetal growth pattern

I wouldn't say juvenile, but immature instead. It could be a sub-adult, or it could be a juvenile. We don't know, so just call it immature.

I would rely on that image only to a certain extent. As you can see, Hartman used C. nasicornis remains to fill the gaps with C. dentisulcatus, so that is why they look so similar in the image.
