"Stallion" saddles are Asian junk. They may look cool, but they are not worth the price to ship them.
The second link looks about the same.
These cheap leather saddles are made with inferior leather on soft wood (pine) or fiberglass (sometimes called fiberflex) trees. The trees are often warped out of the box. If you are lucky enough to get a straight tree, they often fit the horses oddly and can warp or crack over time. They are not made to last. The metal hardwear will be nickle plated steal. It will pit, rust, and corrode over time. If you're unlucky, it can break.
Abetta saddles are made in the USA on quality USA made Ralide trees (a good brand name of trees). They don't last as long as a good leather saddle, but they will hold up to use better than an Asian import, and you can trust their trees and workmanship to good.
If you want a leather saddle, look for an older brand name saddle.
