I'm just not a prong fan, that's all there is to it. Just my opinion, obviously, and like I've said, I know some people prefer them and find them useful.
One of my dogs isn't treat oriented and is extremely stubborn, but she has been successfully trained with strictly positive reinforcement. I'd say it probably took alot longer, and I understand trainers have a limited time to "train" people's dogs in a group setting, so time isn't on their side and thus probably the reason many trainers prefer such tools.
I don't have a problem with negative/compulsion training on dogs that are in a dire situation and have a behavior that needs to be fixed fast or else, but generally I much prefer the positive.
Just my opinion/experience. Everyone's different.
