I'm a bigger fan of hybrids....because hardiness is important to me. Fewer crises=more production, whether it be for dairy or meat. Since dairy is more important to me right now, I am using dairy bucks, four of my six does have heavy meat goats in their backgrounds....two pygmy-x's and two with Boer in them.
The two with Boer in them are interesting. It will be interesting to see what they can produce as far as milk is concerned. Ginger is 1/4 Boer, 1/4 Alpine, adn 1/2 Nubian, so 3/4 dairy, but she is hefty and has the thickest coat that allows her to be out in the rain and snow. Her daughter is the product of a purebred La Mancha buck, so she is 7/8 dairy and 1/8 Boer and looks like she will be just as big and sturdy as her momma. If they can "put it in the bucket," they will be the perfect homestead goats.
I will see what my pygmies give me with the Alpine buck they are bred to. They have been completely free of any health issues in spite of neglect in their early year or two, before I got them. Or maybe because of it.
