I have sheep, and I enjoy keeping them. They are hair sheep, so don't have to be sheared like wool sheep. They grow a coat in the winter that they shed in the Spring. Many people keep sheep together with goats and they are fine on pasture together or feeding hay. Goats are friendlier but also harder to manage than sheep (IMO) as they are harder to confine and less respectful of your personal space. However, having 3 or 4 of either would not be too difficult. If you want to breed, Billy goats are kind of smelly. There can be individual preferences as to taste if you are going to eat them. Hair sheep taste more like deer than wool sheep. I have 2 1/2 acres and they help me keep down the weeds. They are prolific breeders, but without a male you will not have to worry about that. Oh, and as far as eating goes, my sheep are just a prone to eating bushes and trees and will often preferentially eat them, so I have to fence them off from said targets. On the other hand, goats would be harder to fence off from the shrubs/trees as they are not really very respectful of fences and like to escape.
