Bottom line, get a breed of goat that just reaches out to YOU! There are extremely nice show goats in every breed, but not every breed is for you. Good luck in your search.
I would say visit goat farms and go to goat shows. Our county fairs had every breed of goat there. Those are a great chance to see all the different breeds under one roof. You will definitely find that breed that you think is wonderful. I love my Nigerians but I also like Nubians. But that is my personal choice.
