What is the best horse in Red dead redemption

• The two fastest are the American Standardbred(fastest) and the Hungarian Half-bred(second fastest).The Hungarian Half-bred is found in Mexico and the American Standardbred is found in Tall Trees.
  

There is also the Kentucky Saddler which can be found in the Cholla Springs area. And I believe there is a white horse that can be found in Mexico. I cannot recall the name. Sorry.
