For the classical (and any dressage) if I could choose it would definitely be an andalusian horse. They are so intelligent and have the great temperamant, event the stallions, that they are easy to train and are born with the natarul "collection", which is a bonus to them. Whereas the warmbloods that I know, some of them can be can be "hot tempered" not all of them though! And are quick learners . I agree that a spanish horse isnt suited to jumping as their build are more "dressagey" if you know what I mean. But the warmbloods are excellent jumpers....sooo...
The spanish horse for me! But then again....the warmbloods do have better movement at the pirroutte and flying change and are take extensions better..
Oh I don't know I like them both!
