Which is better, Milan Mona Lisa or Royal Mona Lisa?

Mona Lisa is a famous portrait masterpiece. It represents leonardo da vinci's highest artistic achievement and successfully shapes the image of bourgeois women in a city during the rise of capitalism. The figures in the painting sit gracefully, with implicit smiles and deep mountains and rivers as the background, vividly showing the painter's unique smoky "unbounded gradient coloring method"-like brushwork. The painter tried to skillfully combine the rich inner feelings of the characters with the beautiful shapes. For the key parts of the portrait face, such as the corners of the eyes, lips, etc., he also pays special attention to mastering the dialectical relationship between precision and implication, so as to achieve the charm, thus making Mona Lisa's smile have eternal mysterious charm, which is called "mysterious smile" by many art historians.
