Neither is better than the other. Neither will hurt your dog. They're both fine to use, some people use one or the other depending on the situation and how easy/hard something might be to shape.
Free shaping is just more fun for some, and more of a challenge.
I use both, personally.
Thank you for clearing that up. If neither hurts your dog, I will use what I know in the beginning for the basics. Lure. Thank you.
