Where is Su Shi's calligraphy worse than Mi Fei's?

From which angle should we look at this problem? If Mi Fei, who only talks about skills, is richer, more turning and jumping than Su Shi, if we look at the realm of calligraphy, it is obvious that Su Shi is deeper and more interesting, which mainly comes from the nourishment of Su Shi's extensive literary literacy. However, Su Shi's calligraphy has never been well learned, and later scholars made Su Shi's calligraphy style even and neat, and learned to death, especially in the contemporary era! Only Dong Qichang realized this. He subtracted the unsuitable parts of Su Shi's ci and absorbed its essence. Miffy didn't mention it. Since the birth of Mi Fei, almost no calligrapher has been unaffected by it. He was a master of calligraphy in Jin and Tang Dynasties. I've been thinking that we've been talking about two kings and two kings, but we all focus on the king and seldom pay attention to the word "dare". Mi Fei was deeply influenced by Wang Xianzhi's calligraphy. From this perspective, has Miffy been influencing him?
