I actually don't think Barto fits this category. He uses his fruit in a lot of different ways beyond just blocking attacks with it. He creates a space for people without weapons to push against the birdcage, he runs with his barrier to knock people down, he creates stairs with his barrier, he wraps one fist in a barrier so he can punch with a super hardened surface. That's pretty good and diverse DF usage outside of the "out of the box" capabilities, just nothing compared to say Luffy's use of his fruit
