Jingding or Du Cheng, who is better?

Ding and Du Chengdu are famous martial arts equestrian performers. In terms of skill and unconstrained style, Du Cheng should be the best. Ducheng has a deeper grasp of martial arts equestrian, especially in the unrestrained palm making, which can achieve extremely magical movements such as flying to the ground, taking off and landing in the air, turning around and turning around, which is difficult to imitate. Ding's technology is superb, but it is not so extreme compared with Du Cheng.
