My very first horse was Cocoa, a QH (who I still have actually) and then last year I got a TN Walker, Angel. Although I loved loved loved her gait, I have to say that selling her and getting another QH (Toby) was the best move I ever made.
They are versatile, honest, level headed, good horses. Toby is a great companion and a terrific horse.
So even after all these years, QH's are still my favorite breed to own.
