What wins at shows (not just in poultry but every animal) is what judges/breeders want which sometimes gets away from original standard of perfection. In other words, show standards change over time and whims of breeders/judges.
An example is hamp hogs. They have upright ears but in shows what started winning were crosses that had duroc blood in them giving them longer bodies, got rid of muscle tightness and also got rid of their upright ears.. They called it the western strain of hampshires............. Now crossing in other breeds to improve lines is common (I have no problem if they are then line bred to get back to standard).
Breed whatever you want as it is a hobby and very few make a living breeding to the standard of perfection. I've never concerned myself in what wins at shows but what I want which includes standard of perfection.
