I voted for the choker, but I wouldn't say I prefered it.
Kia was in an obedience class taught by a woman who is revered for her skills in training police canines. She trained dogs with the choke/prong collars. Our class was only large breeds... shephards, pit bulls, huskies, etc.
If I were to do it again, I'd try the clicker method first, but I see no problem with using those collars for training if all others had been exhausted.
I no longer use the choke collar on Kia because for the most part she obeys and it served it's purpose.
