Their elegance leaves a little to the imagination. It's very obviously "to hurt or take down, regardless", while some martial arts have a little more complex ways to take an enemy down as simple as they may seem. Don't get me wrong, I can appreciate a tough Muay Thai fighter or a speedy and powerful boxer but their martial arts are ones I'd never practice. I'd like to see opponents dominated physically and mentally, without hurting them too much, so they realize that there's no point in fighting (lulz). So those are the ones I like.
