It's not clear, no. CT is another language for abstraction and the same argument as always hold: languages are equally expressive so it's "just a matter of taste" as to what you use. Category theory emphasizes focusing on the relations between thinfs instead of the things themselves. This can be a natural fit for some theories. For instance, anyone studying probability theory knows that random variables are already functions instead of "objects" but they are the primary thing to study. The CT-minded expression of probability theory is obviously equivalent to the Kolgomorov one, but takes that r.v. emphasis further. You can decide whether or not that's a good thing.
