YMMV, but the problem I have is that it generally makes ugly shapes unless you are very skilled/practiced with it and very careful about twiddling parameters, because the control parameters are based on the implementation details of the mathematical tool rather than directly on features of human perception.
There’s basically a mismatch between human-centered goals and the mathematical model of those.
As an analogy, you might think of it like trying to learn how to dance vs. learning how to make a puppet dance by manipulating a control bar with your fingers to pull on its strings. The latter involves more indirection, which makes it harder for novices to get approximately their desired result.
