I don't use rope halters much, but consider them an 'in between, far as a plain nylon halter and a stud shank.
They won't stop ahorse that really has gotten smart about pulling away, by just bolting suddenly, but they will get a horse a bit lighter, that has no major issue
I never leave halters on, and never use a rope halter routinely, because, to me, it is like always using a twisted wire snaffle, versus just using it short term, to get the horse more responsive again, then going back to that plain web halter. I don't tie with a rope halter-ever
A stud shank, used correctly, just like spurs, does not intimidate a horse, make him fearful, is abusive, as a horse learns you have that stud shank run under the chin, just like ahorse that knows you ride with spurs. Both then, respond to light leg or lead shank alone, long as you always ask first, then demand. Spurs used correctly, keep a horse light while riding. A stud shank does the same, used on the ground, run under the chin, where it never comes into play, IF that horse gives lightly to that lead shank, keeping slack, or to that lunge line, for that matter, which is just a longer form of that lead shank.
Watch a showmanship pattern. Those horses are very light in hand, never engaging that stud shank run under the chin, same as a horse ridden correctly with spurs, seldom needs to be touched with those spurs, yet responds to invisible leg aids
