The first statement is the most accurate: "The meeting between the Aztec and Cortés was friendly; Cortés came back and conquered the empire at a later date. Pizarro’s intent was to conquer the Inca, and he attacked them at their second meeting."
In summary, the initial interaction between Cortés and the Aztecs was characterized by curiosity and civil exchange, while Pizarro's approach towards the Inca was more aggressive and focused on conquest from the outset.
