There is a difference. Your QH hunters are the horses that you ride at the end of the buckle on the reins with no or hardly any contact, their gaits are slower and the headset is low (peanut pushers is what I like to describe them as) and the traditional hunter is more of a forward moving horse, the strides are bigger, they have direct rein contact with the horse at all times, the horse is moving on the bit with them coming up and becoming round. If you're instructor is saying that your horse is a QH hunter it isnt necessarily a bad thing at all. If you want a more tradtional hunter you're going to have to teach the horse to come round with his body, have constant contact with his mouth and really teach him to to engage his hind quarters. As for personality, in both hunter worlds the horse should be quite type of horse. Judges look for a horse that looks easy to ride and seems to listen well.
