OK..so out of these prong/pinch collars which is best.

The Top Paw chrome pinch training collar is a popular collar for controlling leash pulling among dogs of all sizes. The collar has a formidable appearance because of the pairs of metal prongs that point in towards the dog's neck. Used correctly, it is actually a humane training tool. Unfortunately, many people do not understand how to use the collar and risk injury to their dogs as a result. This style of training collar must be fitted correctly and used correctly, for safety as well as good training results. A pinch collar is intended for use only during a training session, and never for all day use.

Herm Sprenger makes excellent quality prong collars. I have not tried the other brand you mentioned, but if you look at some of the prongs sold at pet stores (Petsmart, for example, carries the "Top Paw" brand) you will see how some of their prongs aren't even rounded at the tips but flat, for example. They're just not nearly as good quality as the Herm Sprenger ones.

The Top Paw Snap on Training Collar features hand welded chrome plated links .. Mine does not have a latch. At first, it was a little tough to get on and off, but with practice, it's not that bad. My biggest challenge is just getting Buster to quit wiggling long enough! The Top Paw one I have does not have sharp prongs....in fact, no prong collar should have "sharp" prongs. The tips should be rounded, not pointy. I put the collar around my upper arm and pulled it sharply, to make sure it wouldn't hurt Buster. It was uncomfortable, but didn't even leave red marks on me.
