I haven't found any to be effective with a dog who really wants to chew.
Supervision is the best deterrent - and redirection with appropriate chews.

At least the dog was thorough! I've always preferred teaching a dog what is and is not okay to chew on, as opposed to sprays and such...I had at least one dog who considered Bitter Apple a condiment. Then she ate a sleeper sofa.
It was my sister's sofa and really ugly. When my dog was done with it, I could carry the remains out to the trash in one trip.
