I have not read Mandelbrot's book (yet!), so I can't really compare it.
I don't know what sort of depth you're looking for, but I'd call CBoN a "medium"-depth book on the subjects involved. It's possible to read it like a pop-science book and still appreciate it, but you can actually sit down with pencil and paper (or write some code) and gain a pretty good level of insight. You're not going to necessarily gain a complete understanding of all the underlying math, though, just by reading this book.
Anyway, it's a pretty darn good use of $40, IMO. Buy it!
