I normally do not judge by the looks - but more so how they handle. And how pleasant they make themselves to ride near/around. that said, in the past I have caught myself saying 'uuuugggh' when I see a hot Arabian coming on a trail. I guess because I've seen so many who are hot headed, prance and buck, and create havoc on a nice once-quiet trail ride. lol But that behavior is annoying no matter the horse.
