Holsteiners!!!!! I have one and she has SCOPEEE :)) but most of them are super athletic and have good confirmation :)
Yea warmbloods and thoroughbreds! But also I have two quarter horse crosses and they jump amazingly! Sooo I think if you get a quarter horse crossed with something nice it can be good. I mean you never really know.
Warm bloods are amazing jumpers and thoroughbreds I know are usually race horses but they are actually pretty good jumpers!
warmbloods are probably the best overall!
