Are you sure there is only one solution for cos(x)=0?
both have an infinite number of solutions. cos(x^2) = 0 has broader distribution of solutions compared to the linear and equally spaced solutions of cos(x) = 0. cos(x^2) = 0 is more dense in unique values.

That's correct.
But can one argue that one infinity is larger than the other? They're both infinite...

On what domain, sir?

Infinite domain. The real number line.
I should have been clearer, indeed.
