I wrestled for 7 years and was an active coach (on the mat with the athletes) for 6 years and I was very fortunate to basically have thicker cartilage around the upper curve of the ear and some scarring around the right earlobe (I have detached earlobes and they were constantly getting ripped/torn where they go into the side of my head). I have many friends active in the sport who have cauliflower and some who don't. It seems very genetic or based on your ear anatomy whether you'll get it bad or not. FWIW, Ben Askren's younger brother Max has the worst set of ears I think I've ever seen. He's not an ugly dude like Ben is, but his ears look like some kind of toadstools stuck to the sides of his head...like they puffed out instead of shriveling up.
To answer the question, I think there are some situations where having it would be a seal of approval or badge of honor, but more important situations (professionally) where they'd be a hinderance in terms of people judging/stereotyping.
