Ah I think the OP dog doesn't stop pulling so chokes. With some dogs pressure on the neck does not seem to stop the pulling, ithers a slight scheck and they stop right away. I have one of each, my youngest hates pressure under her ears.
I went through every type of show collar because as soon as I moved it up her neck to keep the head up off the ground she would shake her head in irritation or hold back on the move, spoiling the movement.
I have found I simply had to apply minimal pressure to the lead and keep her with me and interested by voice only, but that is just for the ring situation. She is fine on her round leather half check on normal walks, but I am not worried about her getting her head down more then.
Head collars are very useful for various reasons with wven well trained dogs. they alow you to have more control over large, strong or reactive dogs without having to use brute force,a dn for many people trun a chore into a pleasure and save the owner from injury.
they also make it easier to get into shows with several sniffy dogs and all your parphenalia, especially with males who then have to annoint every sniffed spot.
