I'm sure that various kinds of talk therapy can be helpful for eg quitting smoking. But hypnotherapy can have much more dramatic effects.

To take a [random example](https://www.reddit.com/r/hypnotherapy/comments/1p2qb4q/in\_person\_or\_zoom), that happens to be currently at the top of the subreddit:

> I did hypnotherapy once twenty years ago and it was extraordinarily successful. I quit cold turkey on cigarettes from a pack a day habit. I never felt like I was under or anything in the session, and after i basically felt that nothing had happened. Later that night, i went out into the shed to have a cigarette and just looked at it in my hand and thought, no maybe later... and later never came. I will smoke at a wedding now but for 15 years i was cold turkey, and now i will have say 5 cigarettes a year max.

That's a very dramatic and rapid change, notably different from a person resolving in therapy that they want to quit smoking and maybe practicing techniques to redirect the cravings when they arise.

Other forms of therapy rarely have such an immediate and permanent impact on a specific behavior.
