Both are downhill, second horse worse than the first.
HOWEVER, I like the second horse more than the first overall. First horse has a long back, I don't like the shoulder, and that hindquarter is less than ideal.
Second horse's hindquarter is worse than the first, but shoulder is better, as is back length.
Not going to comment on the necks, I don't like either. Pastern angles are nice on both, first horse's are perhaps a touch on the long side but that might be an illusion created by those LOVELY short cannons. Second horse's cannons are long.
Neither is ideal... but then, Hickstead was slightly downhill and absolutely NOT built to jump, and look what he could do. There are always the incredible few that defy their conformation.
