Whose handwriting is the best in the history of calligraphy?

I think it's Mao Zedong, a great modern man. His mind is open-minded, his poetry is atmospheric, his book style is tough, and his words are magnificent. The cursive school is better than the ancients. The ancients, Zhang Xu and Huai Su, were addicted to alcohol and wrote calligraphy in one go. Although free and easy, it is not as gorgeous as Uncle Mao. Mao Zedong, a great man, is full of revolutionary ambition and strategic thinking. His calligraphy will also be a free and easy masterpiece!
