Right now I have Nigerian Dwarfs and Alpines. I"m looking to add a Nubian to my little herd also.
All goat breeds are wonderful in their own ways. You just need to see if you can find people near you with different breeds so you can actually go interact with them. Then, you need to decide what you like the for you.
Some breeds have long floppy ears like Nubians, some have more pointed up ears like Alpines, some don't have ears like LaManchas. Some have beards, some have horns ... continue to do your research and decide what you like and then find the breeds that have or don't have what you are looking for.
Do you want a large goat breed or a small goat breed (Nigerian Dwarf, Pygmys, Fainting)? Do you want to milk or just have pets? Do you want to pack with them or have them pull a cart? Do you want to use their fiber?
I have all girls right now as I'm milking. If I just wanted pets I'd get wethers and probably small breeds. I like goats with different colors so I went with breeds that aren't solid white. I don't like horns on my goats so I only bought goats that had been dehorned. I like goats with ears so I didn't buy a really nice LaMancha milk goat I looked at - nothing wrong with her... I just think they look funny. I have friends who love that look.
