What is the main difference between A.I. Oparin and J., Haldane on the Origin of Life?

Both scientists adhered to the hypothesis of the origin of life in the process of biochemical evolution of carbon compounds. But unlike Oparin, who considered the coacervate system to be primary, Haldane put forward a hypothesis where the macromolecular system, capable of reproduction itself, was primary. In other words, A.I. Oparin gave priority to proteins, and J. Haldane – to nucleic acids.
