Kkl rating at least.
Having done both, I'd say not really. A dog can not only pass the CD/CDX but get a really good score even if they almost flinch or crawl through the exercises. I find the openess of the SchH field to be a much more difficult distraction then the obviously contained AKC ring, and the group part is pretty easy to practice if you have a few friends with dogs, trained or not. The CGC test, while commendable, is pretty easy to rehearse a pass and have nervy dog get a certificate. I know that it makes sense to have every test be exactly the same because Americans want everything to be fair, but it does lead to a less than true reading of the dog's character in many cases. I was at an fun event a few years back and we had 6 dogs with us, they were doing CGC tests as a fund raiser. We had never done the test but decided to enter ours for the heck of it. Of course ours were all at different levels in their training, but what the heck. They all passed with flying colors and so many of the spectators and testers just gushed over our dogs. We were shocked that they were so impressed at what we considered basic minimum skills.Not that familiar with AKC/CKC style obedience either, but I would say that a BH is equivalent to a CGC/CD/ and some elements of the CDX.
I'm not saying they all do by any means, but I have seen it MANY times. I don't think that people shouldn't participate and work towards the AKC titles, but I will stand by my opinion that the Kkl was intended for the GSD as a way to preserve the breed and it's abilities and traits. Capt. von Stephanitz devised the system to continue the breed he created and loved and I for one don't feel like anyone has come up with anything better or even equal.Just came from an AKC trial and didn't see any dogs flinching or crawling through the exercises-
