Who made greater achievements in the running script of Su Shi, Mi Fei and Zhao Mengfu?

Su Shi's Huangzhou Cold Food Poetry is called one of the three major running scripts. The three major running scripts are Preface to Lanting, Ji Ming's Manuscript and Huangzhou's Cold Food Poetry. Personally, the achievements of the three of them are not based on who is higher or lower, but only on ideological differences. Each of them has his own unique things in it, and can't be judged by level.
