What is the right breed of horse for ...

Just cross posting from other forum! Thought it was an excellent idea to ask....and wonder what you all thought of it?

How do you know you are picking the right breed of horse for you? Now I know a lot of the time it's horses for courses and it depends on what you want to do with them, but how about their personalities and traits, would certain breeds suit certain people?

I know there are websites for dogs where you answer questions and it tells you the best types of breed for you - would this work with horses?

Would be interested in everyone's thoughts!
