no style is the best, every style has something to offer to any human. We all have two arms and two legs so whatever style you do there is someone who can beat it. You have to think individual as well, I know old school karate guys and taekwondo guys that are very tough and could really kill someone. It depends on size, strength, speed , toughness, etc. So many things come into play for fighting , Mike tyson was short and stocky but dominated boxing because of his power and speed and killer instinct. I know people that can knock a guy out with one punch and they never trained in any style. Its a matter of individual, than the style comes after that. How many kids do boxing? ALOT, but how many make the MILLIONS later on, VERY FEW, WHY? TALENT PLAYS A BIG ROLE.
