There has been some confusion I noticed regarding horse saddles as people are unsure of the differences between them or how big those differences are. I have also had to go searching for the differences myself.
This guide is based on a video by just horse and other research.

Dmg resist= bad
Good for Stamina and Speed
Savage:

Durability: 385

DLC Saddles
1. Noble same as Aquilonian
2. Turan, Khitai Scout, Yamatai same as Savage
3. Politain, Silent Legion same as Warhorse
I have not yet noticed a difference between light, medium and heavy warhorse saddles, any light shed on this is welcome
To explain the stats:
The Stamina and speed are both based on the same distance in different saddles.
Lower Stamina % means horse uses less endurance to cover the same distance.
The seconds is how long it takes to cover the same distance. So less time is faster.
