You can mix. The choice makes utterly no difference. All the breeds overlap in performance, and within each species there will be good performers and bad ones. I'd say pick on looks alone. We raise Nubians because I like how they look. If I had liked how oberhausies looked, I would have raised them. But, I didn't.
We milk 3 goats here which is ample for a family of 3, gives us tons of chevre to eat and trade and keep us un too much milk (a lot goes to pigs) most the time
