It seems to me that gradients are used for climb and FPA (degrees) is used mostly in respect of descent. They are two methods of arriving at the same answer. One is rise over run, and the other is opposite over adjacent.
Wind is a red herring, but you understand that part of it anyway. Wind gradient, which of course is an unknown value that aint included in the ATIS, is splitting hairs!
