This, exactly. Those shorter, stocky, QH types are ideal for me because I do a lot of ranch/cow work but someone who rode dressage or liked to do jumping would never look at a horse like that simply because it isn't ideal for them. Along that same line, I would never look at a 17 hand Warmblood type because they aren't ideal for what I do. A person just looking for a horse to plod around on riding trails or even some local small-time shows would get along with just about any breed so they need to choose a horse with a body size and style that suits their preferances and a temperment that compliments them.
