I have no experience with Kyokushin so I'll try not to talk badly about it, but...in real fights, people throw punches at your face, not your body. Being hit in the face is different from being smacked in the body, which you don't seem to realize judging from your post. If you get popped in the nose, your eyes water. If you get caught with a good shot, your equilibrium is thrown out of whack. If you get your nose smashed, you have trouble breathing. These are things that don't happen when dealing with body shots, so Kyokushin practictioners aren't prepared for them, no matter how well conditioned they may be.

Also, defending punches to the face is vastly different from defending against body shots. Slipping, parrying, ducking under, and using footwork to avoid shots are all taught in boxing/MT, as well as how to block them outright. The defensive moves for dealing with body shots don't translate into defending a shot to the dome.

That being said, Kyokushin does seem to be one of the better TMA's in terms of being valuable to MMA or coping with the superior striking of boxing or Muay Thai. From what I've heard conditioning is highly prioritized and the strikes do seem to be grounded in practicality, at least as far as the punches are concered. But if you're truly confident in your ability, go spar with some boxers or Muay Thai fighters and see how Kyokushin compares. I believe you will find it to be enlightening.
