I feel the first one is the poorest conformation wise. He is still a nice horse though (so please don't take it that I think he is of poor quality). His shoulder is more upright than I like (even though it has some length to it), his hocks are higher set than what I like and he looks like he is over or offset in the right front. Going on what the RF looks like, I'd say he is a race bred, Easy Jet horse.

The second one is better balanced (IMHO). He has a better slope to the shoulder (even though the length in a touch shorter than I like). He has lower set hocks. I like the length f his neck. His bak might be a touch long. But overall he is just better balanced to me.

The third horse is a nice horse. But he is heavier up front than I personally like.
