The correct answer to this open question is the following.
I think Michelangelo Buonarroti was the I believe that Leonardo da Vinci was the most talented artist of the Renaissance because of the diversity of his work, the details of his art, the knowledge he had, the people he surrounded it with, his revolutionaries ideas, and the legacy he left to all humanity.
As a painter, his famous paintings in the ceiling of the Sistine Chapel in the Vatican are one of the most impressive pieces of work of all time. Just Michelangelo could have done that. The details, the colors, the expressions, the proportions, and the meanings are simply spectacular.
Regarding sculpture, he had many and all of them "out of this world." For instance, "David," "Moses," and "Pieta." These sculptures in white marble are a true treasure for humanity. Everything is almost perfect. The details in the body of David, the veins in the hands of Moses, the sadness expression on Mary's face (Pieta). Fabulous!
