AQHA hunters and USEF hunters are judged by two completely different rule books. AQHA is heavily influenced by the breed stardard, which is as it should be, since it's a breed show. They're looking for a horse that conforms to breed type and demonstrates the versatility and athleticism of the breed. USEF hunters are about the *discipline* standard, not the breed standard. I'm not saying that one's better or worse than the other, just that they're different and judged on different criteria. A horse that's successful in one is not necessarily likely to be successful in the other.
