I use both and can't say I notice huge differences between them. Also, running another product down like this on a public forum could be legally challengeable, you'd have to have some pretty sound evidence.
T&T, I'd give your goats a good mineral supplement, whichever you decide on, but maybe get them checked out too, as Anke suggests, there could be other things going on there.
Whereabouts are you, maybe one of us is local to you and can help with a bit of mineral for now?
