Which is the best horse in world?

It's impossible to say definitively which is the "best" horse in the world! Here's why:

* "Best" is subjective: What makes a horse "best" depends on what you're looking for. Are you talking about:

* Racing ability? Different breeds excel in different disciplines (sprinting, endurance, jumping, etc.)

* Temperament? Some horses are naturally calm and gentle, while others are high-spirited and athletic.

* Beauty? Horse beauty is in the eye of the beholder!

* Horses are individuals: Even within a breed, each horse has its own unique personality, strengths, and weaknesses.

* There's no objective ranking system: There's no single, universally accepted ranking of horses based on any criteria.

Instead of trying to find "the best", focus on what you're looking for in a horse. Consider things like:

* Your experience level: Do you need a horse that's beginner-friendly or more experienced?

* Your riding goals: Are you interested in racing, trail riding, showing, or something else?

* Your lifestyle: How much time and money can you dedicate to horse care?

Ultimately, the best horse for you is the one that fits your needs and personality!
